The Effects of Pediatric Acute Lymphoblastic Leukemia Treatment on Cardiac Repolarization.

Background: In recent years, cardiac dysfunction in childhood cancer survivors has become an important issue. Studies are focusing on identifying means for the early identification of patients at risk. Considering this, our study aims to investigate 24-hour Holter electrocardiogram (ECG) repolarization changes throughout doxorubicin (DOX) and cyclophosphamide (CPM) administration in pediatric patients treated for acute lymphoblastic leukemia (ALL). Methods: This was an investigator-driven, single-center, prospective, observational study. Enrolled children had a baseline bedside ECG examination performed before starting chemotherapy (T0). Serial Holter ECG examinations were conducted at three moments during their treatment protocol: day 8 (T1), day 29 (T2), and day 36 (T3). This study evaluated several ECG repolarization parameters, such as the QT interval, corrected QT interval (QTc), and QTc dispersion, as well as ST segment variations. Results: We evaluated 37 children diagnosed with ALL. The T0 examination revealed that over a third of patients had a resting heart rate (HR) outside the normal range for their age and sex. During chemotherapy, statistically significant increases in both HR as well as QT and QTc dispersion values were noticed, especially during the first DOX administration. What is more, a significant increase in the percentage of patients with ST segment depression from T1 to T2 and T3 was noticed. Rhythm disturbances were rare in the study population, with only a few patients presenting ventricular or supraventricular extrasystoles. Conclusions: This study reveals silent repolarization changes occurring early during anticancer treatment in children treated for ALL. These findings could aid in a better understanding of the cardiac toxicity mechanism, and they could potentially improve cardiac risk stratification for oncologic patients. Because of the small number of patients, our results need to be validated by larger studies.

Rare within Rare: A Girl with Severe Haemophilia A and Turner Syndrome.

A coincidental occurrence of severe haemophilia A and Turner syndrome in a female person is extremely rare (less than 10 cases published). In such challenging cases, a multidisciplinary approach based on medicine of precision with full access to genetic and bio-molecular exploration is indispensable. The article presents an eight-year-old girl, with a family history of haemophilia, without significant disease signs (only post-dental extraction bleeding and a shorter stature). Discordantly, however, the investigations revealed a challenging condition: a genotype of 46,X,i(Xq), with an Isochromosome Xq responsible for the Turner syndrome and simultaneously, for the detrimental transformation, interfering with X chromosome inactivation, of an obligate hemophilia carrier into a severe hemophilia case-two distinct and provocative diseases.

Anthracycline's Effects on Heart Rate Variability in Children with Acute Lymphoblastic Leukemia: Early Toxicity Signs-Pilot Study.

Anthracycline treatments are known to cause cardiotoxic long-term side effects in cancer survivors. Recently, a decrease in heart rate variability (HRV) has been identified in these patients, signaling autonomic dysfunction and altered cardiac fitness. This study aimed at evaluating changes in HRV in children treated with anthracyclines. A total of 35 pediatric patients with acute lymphoblastic leukemia were evaluated by means of a 24 h Holter ECG, at baseline and after reaching half the total cumulative dose of doxorubicin equivalent (120 mg/m2). Parameters of HRV were assessed, as well as any arrhythmic episodes, bradycardia and tachycardia percentages. The results showed a significant decrease in both time-domain and frequency-domain HRV parameters, following anthracycline treatment. The low-frequency (LF) to high-frequency (HF) parameters' ratio also displayed a significant difference (p = 0.035), suggestive of early cardiac autonomic dysfunction. Of note, none of the patients presented symptoms of heart disease or elevated troponins, and only two patients presented echocardiographic signs of diastolic dysfunction. The present study showed that cardiac autonomic nervous system regulation is compromised in children treated with anthracyclines even before reaching the total cumulative dose. Therefore, HRV parameters could be the first indicators of subclinical cardiac toxicity, making Holter ECG monitoring of the oncological patient a necessity.

Multisystemic Inflammatory Syndrome in Children, A Disease with Too Many Faces: A Single-Center Experience.

BACKGROUND AND AIM: Multisystemic inflammatory syndrome in children (MIS-C) is a rare and severe condition associated with Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2) infection in children with onset approximately 4-6 weeks after infection. To date, the precise mechanism that causes MIS-C is not known and there are many questions related to the etiology, risk factors, and evolution of this syndrome. We aimed to describe the clinical manifestations, treatment methods, and disease evolution and analyze the main risk factors for MIS-C in children hospitalized in our clinic. MATERIAL AND METHODS: We performed a retrospective study including children with MIS-C followed-up in the 2nd Pediatric Clinic of the Emergency Clinical Hospital for Children Cluj-Napoca, Romania, for 13 months (November 2020-December 2021). RESULTS: We included in our cohort 34 children (mean age 6.8 ± 4.6 years) who met MIS-C criteria: high and prolonged fever associated with organ dysfunction (heart, lungs, kidneys, brain, skin, eyes, bone marrow or gastrointestinal organs), and autoantibodies and/or polymerase chain reaction positives for SARS-CoV-2. Nineteen patients (55.88%) had a severe form of the disease, with multiorgan failure and shock, and myocardial or respiratory failure. The number of organs affected in the severe forms was significantly higher (more than 6 in 73.70%) than in mild forms (2-3 in 60%). Cardiac dysfunction, hypoalbuminemia, hypertriglyceridemia and hyponatremia were more important in severe forms of MIS-C. These patients required respiratory support, resuscitation with fluid boluses, vasoactive drugs, or aggressive therapy. All patients with mild forms had fully recovered compared to 63.16% in severe forms. The others with severe forms developed long-term complications (dilation of the coronary arteries, premature ventricular contraction, or myocardial fibrosis). Two patients had an extremely severe evolution. One is still waiting for a heart transplant, and the other died (hemophagocytic lymphohistiocytosis syndrome with multiorgan failure). CONCLUSIONS: From mild to severe forms with multiorgan failure, shock, and many other complications, MIS-C represents a difficult challenge for pediatricians, who must be aware of the correct diagnosis and unpredictable, possibly severe evolution.

Biventricular cardiac metastasis from vulvar squamous cell carcinoma.

Vulvar cancers make up just 3% to 5% of all gynecological cancers, and they are most typically found in postmenopausal women. Vulvar cancer distant metastases are uncommon and usually arise late. Only six cases of vulvar cancer metastasizing to the heart have been reported in the literature, and none of them included both the left and right ventricles. We describe the case of a 68-year-old patient diagnosed with vulvar cancer arising from lichen sclerosus, initially localized, treated with chemotherapy, surgery, and radiation therapy. Less than two months after the end of the treatment sequence, the patient returned to our clinic with bone pain. Imaging investigations have shown multiple disseminated metastases, but not in the heart at that moment. Chemotherapy was initiated, and after two cycles, the patient developed an arrhythmia (atrial fibrillation with rapid ventricular rate), which was later determined to be caused by cardiac metastases discovered by echocardiography and computed tomography. Vulvar cancer metastatic to the heart represents a rare clinical condition, requiring multidisciplinary care. The case's uniqueness is the biventricular metastasis, which resulted in STEMI despite angiographically normal epicardial coronary arteries.

Signet ring cell gastric carcinoma with breast and leptomeningeal metastases: a case report.

Gastric cancer is the 5th most common malignancy worldwide. Signet ring cell histology represents an aggressive subtype of gastric cancer, presenting at a younger age. Both breast and leptomeningeal metastases are rare locations of tumor dissemination, requiring correct and immediate diagnosis and treatment. We present a case of a 45-year old female with signet ring cell gastric carcinoma who developed both left breast and leptomeningeal metastases, requiring multiple chemotherapy lines. As far as we know, this is the first published case in literature following multiple lines of treatment for both breast and leptomeningeal metastases from signet ring cell gastric carcinoma.

Why Do Children with Acute Lymphoblastic Leukemia Fare Better Than Adults?

It is a new and exciting time for acute lymphoblastic leukemia (ALL). While nearly 50 years ago, only one in nine children with ALL survived with chemotherapy, nowadays nearly 90% of children have a chance of long-term survival. Adults with ALL, as well as the special category of adolescents and young adult (AYA) patients, are catching up with the new developments seen in children, but still their prognosis is much worse. A plethora of factors are regarded as responsible for the differences in treatment response, such as age, ethnicity, disease biology, treatment regimens and toxicities, drug tolerance and resistance, minimal residual disease evaluation, hematopoietic stem cell transplantation timing and socio-economic factors. Taking these factors into account, bringing pediatric-like protocols to adult patient management and incorporating new agents into frontline treatment could be the key to improve the survival rates in adults and AYA.

Partnering bevacizumab with irinotecan as first line-therapy of metastatic colorectal cancer improves progression free survival-A retrospective analysis.

Colorectal cancer remains one of the most frequent malignancies (third place at both genders) worldwide in the last decade, owing to significant changes in modern dietary habits. Approximately half of the patients develop metastases during the course of their disease. The available therapeutic armamentarium is constantly evolving, raising questions regarding the best approach for improving survival. Bevacizumab remains one of the most widely used therapies for treating metastatic colorectal cancer and can be used after progression. This study aimed to identify the best chemotherapy partner for bevacizumab after progression. We performed a retrospective analysis of patients with metastatic colorectal cancer who were treated with bevacizumab as first- and second-line chemotherapy. Data were collected for 151 patients, 40 of whom were treated with double-dose bevacizumab after the first progression. The two standard chemotherapy regimens combined with bevacizumab were FOLFIRI/CAPIRI and FOLFOX4/CAPEOX. The initiation of first-line treatment with irinotecan-based chemotherapy improved progression-free survival and time to treatment failure but not overall survival. After the first progression, retreatment with the same regimen as that used in the induction phase was the best approach for improving overall survival (median overall survival: 46.5 vs. 27.0 months for the same vs. switched strategy, respectively). No correlations were observed between the dose intensity of irinotecan, oxaliplatin, 5-fluorouracil, or bevacizumab and the overall survival, progression-free survival in the first-/second-line treatment, and time to treatment failure. Interaction between an irinotecan-based regimen as a second-line treatment and double-dose bevacizumab after progression was associated with an improved overall survival (p = 0.06). Initiating systemic treatment with an irinotecan-based regimen in combination with bevacizumab improved the progression-free survival in the first-line treatment and time to treatment failure. In terms of overall survival, bevacizumab treatment after the first progression is better partnered with the same regimen as that used in the induction phase.

Doubling the Dose of Bevacizumab Beyond Progression in Metastatic Colorectal Cancer-the Experience of a Tertiary Cancer Center.

Background: Colorectal cancer (CRC) is the third most common cancer in Europe, with an annual increase in incidence ranging between 0.4 and 3.6% in various countries. Although the development of CRC was extensively studied, limited number of new therapies were developed in the last few years. Bevacizumab is frequently used as first- and second-line therapy for management of metastatic CRC (mCRC). The aim of this study is to present our experience with using bevacizumab beyond disease progression at different dosage levels in mCRC patients, in terms of overall survival, progression-free survival, time to treatment failure, and toxicities. Methods: We performed a consecutive retrospective analysis of patients with confirmed mCRC who were treated with bevacizumab at "Prof Dr. Ion Chiricuta" Institute of Oncology, Cluj-Napoca, Romania. We included patients who had received bevacizumab as first- or second-line therapy and further stratified them according to the dose administered as a second-line (either standard dose of 5 mg/kg every 2 weeks or 7.5 mg/kg every 3 weeks, or double dose of 10 mg/kg every 2 weeks or 15 mg/kg every 3 weeks-depending on the classical chemotherapy partner). All patients had received bevacizumab beyond progression (BYP) which is defined as continuing bevacizumab administration through second-line treatment despite disease progression. In each group, we evaluated the prognostic factors that influenced survival and treatment outcome. Results: One hundred and fifty-one (151) patients were included in the study. Themedian age of patients receiving double dose bevacizumab (DDB) and standard dose bevacizumab (SDB) was 58 years (range 41-71) and 57 years (range 19-75), respectively. The median overall survival in the DDB group was 41 months (range 27-49) compared to 25 months (range 23-29) in the SDB group (p = 0.01 log-rank test). First-line oxaliplatin-based treatment was used more frequently regardless of group, while irinotecan-based more frequently used as a second-line treatment (p = 0.014). Both oxaliplatin- and irinotecan-based regimens were found to be suitable partners for BYP. Statistical analysis revealed that dose intensity, primary tumor location, and cumulative exposure to BYP had significant influence on survival. Conclusion: Doubling the dose of bevacizumab after first progression may improve survival in mCRC patients. Increasing bevacizumab dose intensity could override the prognostic impact of primary tumor location in patients receiving double the dose of bevacizumab after first disease progression.

Paraneoplastic cerebellar degeneration associated with anti-Yo antibodies in an ovarian cancer case: A case report.

Paraneoplastic neurologic syndromes (PNS) are a rare heterogeneous group of disorders associated with malignancy that can result in significant functional impairment. One syndrome in particular, paraneoplastic cerebellar degeneration (PCD), may be severely disabling. PCD is a rare neurological syndrome, associated with active or subclinical cancer, characterized by acute or subacute onset cerebellar ataxia due to tumor-induced autoimmunity against cerebellar antigens. Treatment of paraneoplastic syndromes is generally unsatisfactory, but early diagnosis and treatment of PCD, which includes neurological treatment, immunotherapy and oncological treatment of associated malignancy, may improve the neurological prognosis. We reported the case of a 59-year-old woman who presented PCD as the first sign of ovarian cancer. Laboratory investigations showed the presence of anti-Yo antibodies in the serum. The brain MRI revealed specific modifications for PCD. After oncological treatment, intravenous immunoglobulin therapy and corticosteroid therapy, the oncological response was satisfactory, but no improvement of the neurologic symptoms was achieved.

What to do when nothing else is left to be done - metastatic non-HPV vulvar squamous cell carcinoma with multiple lines of chemotherapy.

Recurrent vulvar squamous cell carcinoma with multiple site metastases is a rare entity - (up to 14.2% of the total number of recurrences), with a poor prognosis (only 15% of the patients alive at 5 years). Due to its "hard to find" character, there are no standardized guidelines available and the treatment is extrapolated from advanced cervical carcinoma, anal carcinoma and other squamous cell carcinomas. Immunotherapy has shown some positive results in vulvar carcinoma with PD-L1 positive, high TMB, high MSI or with MMR deficiency. An alternative for selected cases without therapeutic resources could be the HPV vaccine. We present the case of a 64-year-old woman diagnosed in 2014 with vulvar squamous cell carcinoma stage II for which she underwent radical vulvectomy with bilateral inguinal lymphadenectomy followed by external radiotherapy. In 2019 she developed local recurrence associated with lung, pleural, lymph nodes and subcutaneous metastasis, treated with three lines of chemotherapy: paclitaxel/carboplatin followed by cisplatin/5-fluorouracil and carboplatin/gemcitabine. The patient's general health status altered progressively, and she died after the 4th cycle of carboplatin/gemcitabine. This case's management could be a starting point for the vulvar carcinoma cases where the standard therapeutical options do not represent a choice anymore, providing the necessary example on how to approach it.

Treatment beyond progression in metastatic colorectal cancer: to double or not to double the dose of bevacizumab?

PURPOSE: Bevacizumab or cetuximab represent the standard treatment in association with classical chemotherapy in confirmed metastatic colorectal cancer (mCRC). Bevacizumab could be continued after the first disease progression with an overall survival (OS) advantage, compared to chemotherapy alone, but the optimal dose remains a debatable issue. METHODS: In a retrospective analysis of mCRC patients treated with bevacizumab, we selected patients with administration beyond progression, and stratified them according to the dose received- same dose bevacizumab (SDB) as first-line chemotherapy or double dose bevacizumab (DDB). For each group we evaluated OS, time to treatment failure (TTF) and progression-free survival in the first-line (PFS1) and in the second-line (PFS2). RESULTS: In the first-line therapy, oxaliplatin backbone regimen was used in 73% SDB, compared with 22.5% DDB patients, while irinotecan was used in 75% DDB and 27% SDB patients. Second-line oxaliplatin was given to 50% DDB and 29.7% SDB patients, while irinotecan was administered to 47.5% DDB and 70.3% SDB patients. The median values were: OS - 41 months in the DDB group and 25 months in the SDB group (p = 0.01); TTF - 24 months in the DDB group and 19 months in the SDB group (p=0.009); PFS1 - 17 months in the DDB group and 12 months in the SDB group (p=0.008); PFS2 - 9 months in the DDB group and 5 months in the SDB group (p = 0.03). CONCLUSIONS: Doubling the dose of bevacizumab at progression seems to provide OS and PFS advantage for mCRC patients.

Acute Lymphoblastic Leukemia with Malignant Hypercalcemia: A Case Report.

BACKGROUND Malignant hypercalcemia is a rare finding in the pediatric population, even more rare in hematological malignancies, such as leukemia. CASE REPORT We present a case of a 6-year-old female patient who was diagnosed with acute lymphoblastic leukemia, with secondary hypercalcemia. She started chemotherapy following the IC-BFM ALL2002 protocol with simultaneous calcitonin, diuretics and aggressive hydration for hypercalcemia, and went into complete remission after the induction therapy. After 4 months of chemotherapy, she was diagnosed with relapse associated again with malignant hypercalcemia, and underwent chemotherapy with the relapse protocol. There was no response after the first 2 cycles, so we decided to start her on clofarabine. Due to the severe hypercalcemia and consecutive osteolysis, she developed several bone fractures and needed gypsum immobilization. We started her again on calcitonin, but she developed severe adverse reactions, so we found it necessary to start bisphosphonates, first zoledronic acid intravenously, and afterwards clodronate orally. Consolidation of bone fractures was achieved, but due to prolonged immobilization she developed bedsores, superinfected with Lichtheimia corymbifera. We started posaconazole orally, but she rapidly went into severe sepsis with multiple organ failure. The leukemia showed no response to chemotherapy, progressed rapidly, and the patient died. CONCLUSIONS Malignant hypercalcemia is associated with a poor prognosis in leukemia, and might need a more aggressive therapy.

Combined effect of propranolol, vincristine and bevacizumab on HUVECs and BJ cells.

Infantile hemangioma is one of the most common benign tumors affecting children, with ~10-15% requiring medical treatment. These tumors consist of endothelial cells and stromal components, including fibroblasts, pericytes and mast cells. Effects of propranolol treatment in combination with bevacizumab or vincristine on cell growth were compared in the current study using human umbilical vein endothelial cells (HUVECs) and BJ human normal fibroblasts (BJs) to determine potential synergic effects in vitro. Inhibition of cell growth was investigated using MTT assays and cytotoxicity of the drugs in various combinations was expressed as half inhibitory concentration (IC50). Apoptosis was investigated using flow cytometry, with Alexa Fluor 488 and propidium iodide. Propranolol inhibited BJ and HUVEC growth in a dose-dependent manner, with increased response observed in BJs (IC50, 148,32 µg/ml; standard error logIC50, 0.07). Treatment with vincristine induced the strongest growth inhibition in HUVECs (IC50, 17,89 µg/ml; standard error log IC50, 0.07) and BJs (IC50, 24,81 µg/ml; standard error log IC50, 0.08) compared with propranolol (HUVEC IC50, 81,94 µg/ml; standard error log IC50, 0.06; BJ-IC50, 148,32 µg/ml; standard error logIC50, 0.07) or bevacizumab (HUVEC IC50 96,91 µg/ml; standard error log IC50, 0.06; BJ IC50, 182,70 µg/ml; standard error log IC50, 0.09) alone. Bevacizumab was the weakest cytotoxic agent. Combination treatment of vincristine with bevacizumab induced the highest levels of apoptosis in HUVECs compared with all other treatments and triple-drug therapy induced the levels of apoptosis in BJs. Single treatment with vincristine, propranolol or bevacizumab induced apoptosis in BJs and HUVECs. In BJs, triple treatment exhibited the greatest influence on apoptosis, compared with single and dual treatments and in HUVECs, vincristine and bevacizumab combination treatment induced apoptosis to the highest level. The present study offers novel perspectives in drug repurposing studies for the three drugs, particularly in diseases where the pathogenesis is based on healthy endothelial cell proliferation, including hemangiomas.

The role of biomarkers and echocardiography in the evaluation of cardiotoxicity risk in children treated for leukemia.

PURPOSE: To describe the high-risk profile group, susceptible to develop anthracycline-induced cardiomyopathy in children with acute leukemia. METHODS: The study involved 35 pediatric patients diagnosed with acute lymphoblastic (ALL) or acute myeloblastic leukemia (AML), from March 2014 to December 2016. Serologic markers used for the analysis of cardiac dysfunction were troponin T, NT-proBNP and PCRhs. Also, the patients have had echocardiographic evaluation at the beginning of treatment to determine LVEF, SF and A, E, E' Doppler waves. RESULTS: Positive linear correlation was shown between NT-proBNP and leukocyte values, NT-proBNP and blast cells value, and NT-proBNP and LDH. Significant linear negative correlations between LVEF with leukocyte values, blast cells values, LDH, SF and leukocyte values, LVEF and NT-proBNP values and LVEF and troponin T values were also identified. A weak negative correlation between E/E' ratio and blast cells values has been observed. All of these correlations were statistically significant (p<0.05). CONCLUSIONS: Leukocyte value, as well as the other serological markers assessed (NT-proBNP, Troponin T), are useful tools to evaluate the risk of anthracycline-induced cardiotoxicity. The variation of the biological markers at the beginning of the cytotoxic treatment confirms the presence of an early myocardial dysfunction, emphasizing the importance of systematic evaluation of this particular group of patients.

Infantile hemangiomas: a 7-year experience of a single-center.

OBJECTIVES: The aim of the study was to describe the historical and clinical characteristics of hemangiomas in a series of cases of our clinic. METHODS: This is a retrospective study of 36 patients with infantile hemangiomas consulted in our clinic. RESULTS: We had 14 multiple hemangiomas, and 1 kaposiform hemangioendothelioma. Almost two-thirds involved the cephalic extremity, and 76% of the cases were treated. Pregnancy risk factors included prematurity, low-birth weight and respiratory distress syndrome. Propranolol was used in 22 cases, followed by prednisone in 3 cases. Vincristine and interferon were used as associated therapies or as second line therapies. Two hemangiomas had complications, one ulceration and a Kasabach-Merritt syndrome. All the patients had a good evolution. CONCLUSIONS: Our study results regarding the involvement of pregnancy and birth risk factors in developing infantile hemangiomas is similar to literature data. The majority of patients had at least one risk factor suggesting that at least one trigger to develop an infantile hemangioma is necessary. Our study shows that the cephalic extremity is mostly involved, and because of its potential complications they are most likely to be treated. The study shows that propranolol is the leading treatment option with few and mild side effects.

A malignant pheochromocytoma in a child with von Hippel-Lindau mutation.

Pheochromocytoma is a rare neuroendocrine tumor that arises from the chromaffin cells of the sympathetic nervous system. Over one third of pheochromocytomas are associated with germline mutations. We describe a 3 year-old girl with an inherited right adrenal malignant pheochromocytoma, with the mother diagnosed with von Hippel-Lindau syndrome. Genetic tests revealed the presence of the VHL c 244 C>G (p. Arg 82 Gly) heterozygote mutation in the mother, as well as in the child. After 6 months from the complete resection of the tumor, the patient is without any clinical symptoms, with normal blood pressure, normal ophthalmoscopy, no tumor markers and no evidence of tumor on cerebral or abdominal MRI. Lifelong complex follow-up is needed, as it is known that at a later age VHL mutation may cause retinal angiomas, cerebellar and spinal hemangioblastomas, relapsed pheocromocytoma, pancreatic and renal cysts, clear cell renal cell carcinoma and endolymphatic sac tumors.

Solid pseudopapillary tumor of the pancreas: clinical-pathological features and management of 13 cases.

BACKGROUND AND AIM: Solid pseudopapillary tumor (SPT) of the pancreas is a rare pathological condition, representing less than 3% of all exocrine pancreatic tumors. SPT usually occurs in young females, without notable symptoms, with a low malignant potential and excellent prognosis. METHOD: We conducted a retrospective study during the period January 2005 - January 2015. SPT patients admitted in our institution were reviewed by describing demographic data, clinico-pathologic and radiological features, therapeutic management and prognosis records. RESULTS: Thirteen patients with SPT were identified (10 females), with a median age of 30 years. The main clinical presentation was abdominal pain (92.3%). The tumor was mostly located in the body or tail of the pancreas (77%), and the mean size was 8.2 cm. Regarding the surgical approach there were 5 distal pancreatectomies with splenectomy, 3 body and tail pancreatectomies, 2 body and tail pancreatectomies with splenectomy, 2 pancreato-duodenectomy, 1 partial enucleation and of all only 2 partial resections. Postoperative hematoxylin- eosin staining and immunohistochemistry confirmed the diagnosis in all cases. None of the patients had lymph nodes metastases. Only one local invasion. There was one case of death due to postoperative complications. Four cases followed adjuvant systemic chemotherapy. The mean follow-up was 18 months, without evidence of recurrence during this period. CONCLUSION: SPT should always be considered in the differential diagnosis in young women with a pancreatic tumor. Complete surgical excision is the treatment of choice, and is usually curative. The decision to administer systemic therapy must be individualized. Malignant behavior and late recurrences mandates long-term follow-up for patients with SPT.

Diffuse cutaneous bullous mastocytosis with IgM deposits at dermo-epidermal junction.

Cutaneous mastocytosis is a disease characterized by the infiltration and proliferation of mast cells in the skin. In children, the most common form of presentation is urticaria pigmentosa, while the diffuse cutaneous bullous mastocytosis is one of the rarest subtypes seen. The aim of this paper is to present a case of diffuse bullous mastocytosis with detection of IgM deposits at dermo-epidermal junction using direct immunofluorescence (DIF) microscopy. The diagnosis of diffuse bullous mastocytosis is a challenge, and DIF microscopy is necessary in order to exclude an autoimmune bullous disorder. However, IgM deposits at dermo-epidermal junction can be nonspecific, being found in a variety of skin disorders. A 6-month-old girl presented with bullous lesions and erosions on the scalp and the trunk. During hospitalization, further bullous lesions appeared, along with generalized erythrodermia. Skin biopsy revealed aspects of urticaria pigmentosa. Taking into account the clinical findings, the case was enclosed as bullous mastocytosis. Treatment included the avoidance of trigger factors, and administration of antihistamines along with a short-term course of systemic steroids. The evolution was favorable, with remission of the existing lesions and without occurrence of new ones.

Infantile Hemangioma: A Brief Review.

Infantile hemangiomas as frequent infancy tumors have been a controversial issue of medical scientists worldwide. Their clinical aspects are various and their physiopathology is yet to be fully understood. Numerous publications outline the characteristics, causes, evolution possibilities and therapeutic approaches. Deciding whether to treat or not is the main question of this kind of pathology. Hemangiomas that have complications or can cause irreversible damage need therapy. This is a brief review of up-to-date information regarding the presentation of infantile hemangiomas and target-therapies.
