RESUMO

Serous endometrial intraepithelial carcinoma (SEIC) is a rare but highly aggressive form of uterine endometrial cancer. We report two cases of post-menopausal, 58-year-old patients with abundant vaginal bleeding and pelvic pain. The first patient had a history of surgical hysteroscopy in 2019 for an endocervical polyp. The second patient had a history of breast resection, axillary lymph node dissection, chemotherapy, radiation therapy, and tamoxifen therapy for breast carcinoma 6 years ago. An abdominal hysterectomy was performed in both patients. The pathological assessment showed serous endometrial intraepithelial carcinoma. Diagnosis of a serous proliferation of the uterus implies the exploration of other genital tract organs as well as distant locations in search of metastatic disease.

RESUMO

Clear cell sarcoma (CCS), previously known as soft tissue melanoma due to similarities with melanoma, is a rare and aggressive neoplasm. This tumor predominantly occurs in the lower limbs and rarely affects the tongue, as well as other head and neck locations. To our knowledge, only five cases have been reported in the English literature. CCS presents many similar morphological and immunohistochemical features to those of melanomas, sarcomatoid cell carcinoma, angiomatoid histiocytoma, and Ewing sarcoma, which makes the diagnosis difficult, especially in cases of uncommon locations. The treatment is based on oncological surgery and adjuvant radiation therapy as these tumors show low sensitivity to chemotherapy. This study aimed to report a case of an 88-year-old male patient who presented a large, rapidly growing nodular lesion on the right border of the mobile tongue diagnosed with CCS of the tongue.

RESUMO

The World Health Organization currently divides endometrial stromal sarcomas into 4 different entities, based on their clinical and pathological features: endometrial stromal nodule, low-grade endometrial stromal sarcomas (LG-ESS), High-grade endometrial stromal sarcomas, and undifferentiated uterine sarcoma. The fibroblastic variant of LG-ESS is rare and is usually made of small tumoral cells of oval to fusiform shape, demonstrating low cytologic atypia and low mitotic activity, which can lead to confusion with a benign myofibroblastic proliferation. We hereby report a rare case of a fibroblastic variant of LG-ESS in a 37-year-old woman presenting abundant metrorrhagia, which was initially misdiagnosed as an inflammatory pseudotumor before proofreading in our laboratory, along with a review of a histological and immunohistochemical findings, aiming to help pathologists avoid this diagnosis pitfall.

RESUMO

Trichilemmal carcinoma (TC) is a rare skin malignant tumor with pillar differentiation. TC presents along with other malignant hair follicle tumors and accounts for only 1% of all adnexal carcinomas. TC usually occurs on sun-exposed skin in elderly people, nevertheless, it can occur at any age. We report a case of trichilemmal cyst carcinoma in a 54-year-old woman presenting with an increasing occipital cyst. A histological examination confirmed the diagnosis and a large excision was performed. Despite the absence of a well-defined consensus on the management of TC, surgical excision with adequate margins seems to be safe in the absence of metastatic lesions. However, in the case of second localization, chemotherapy could be initiated, but again, in this case, no consensus on the appropriate protocols exists.

RESUMO

Carcinosarcoma of the gallbladder is a rare cancer characterized by presence of a carcinomatous and a sarcomatous component. In our work, we report the case of a 66-year-old male patient, presenting with isolated abdominal pain evolving for more than 6 months. contrast-enhanced computed tomography enabled identification of a gallbladder mass, invading liver, duodenum and abdominal wall. A cholecystectomy, extended to liver, duodenum and abdominal wall was performed. The final diagnosis of gallbladder carcinosarcoma was obtained by pathological assessment. Gallbladder carcinosarcoma has a poor prognosis. Since it is rare, no established chemotherapy or radiation protocols exist. Further studies about case series are needed to establish better therapeutic protocols. Gallbladder carcinosarcoma is a rare cancer with a rapid progression making therapeutic decisions difficult. All these factors contribute to the poor prognosis of this cancer.

RESUMO

Dysphania ambrosioides (L.) Mosyakin and Clemants is a medicinal plant that has traditionally been used to cure a range of diseases. There has been no thorough investigation of the potential toxicity of this plant. The objective of this study is to assess the acute and subacute toxicity of D. ambrosioides hydroethanolic extract (DAHE), as well as it alkaloids composition, utilizing LC-MS/MS analysis. An in silico approach was applied to determine pharmacokinetic parameters and to predict the toxicity of D. ambrosioides identified alkaloids. A 14-day treatment with a single oral dose of 1-7 g/kg was carried out to investigate acute toxicity. DAHE was given orally at dosages of 5, 50, and 500 mg/kg for 15 days in the subacute toxicity investigation, and body weight and biochemical parameters were evaluated. Livers, kidneys, lungs, and heart were examined histologically. Chromatographic investigation revealed the existence of nine alkaloids, with N-formylnorgalanthamine being the most prevalent. The oral LD50 value of DAHE was found to be 5000 mg/kg in an acute toxicity study. No variations were observed with respect to food intake, water consumption, mortality, or body and organ weight in the subacute toxicity study. On the other hand, DAHE (500 mg/kg) significantly enhanced alanineaminotransferase, aspartate aminotransferase, and urea. Liver and kidney histological examinations revealed modest infiltration of hepatocyte trabeculae by inflammatory cells in the liver and slight alteration in the kidney histoarchitecture. According to our findings, DAHE exhibits low to moderate toxicity.

RESUMO

Dermatofibrosarcoma is a rare cancer, accounting for 0.01% of all cancers. We here report the case of a 44-year-old female patient presenting with the 5th recurrence of locally advanced Darier-Ferrand dermatofibrosarcoma, that progressed on many cycles of neoadjuvant therapy and required emergency radiotherapy with good response. This allowed to perform wide excision of the tumor with healthy limits. The patient had remission after 1 year of follow-up. Prognosis for patients with Darier-Ferrand dermatofibrosarcoma is generally excellent. Wide surgery and the advent of Mohs surgery have improved local control. The role of radiotherapy is limited for non-resectable tumors or positive margins.

RESUMO

Chondrosarcoma is a highly aggressive malignant tumor originating from cartilaginous and mesenchymal tissues. The aim of this report is to describe a rare case of nasosinusal chondrosarcoma with orbito-cerebral extension. Our patient was a 55-year-old with a right cheek swelling evolving over a year, with unilateral right nasal obstruction gradually becoming bilateral associated with hyposmia, bilateral exophthalmos, reduced bilateral deep visual acuity and permanent headaches. The clinical examination found a tumor obstructing the two nasal cavities. Imaging showed a lobulated heterogeneous tissue process occupying the paranasal sinuses, with calcifications and enhancement at its periphery, extending to the orbito-cerebral area. The histopathological analysis was in favor of chondrosarcoma. The patient was first treated with an incomplete surgical resection by an endonasal route due to the extension to the orbit and the brain and received adjuvant radiotherapy. Surgical excision is a prognostic factor in this type of sarcomas and reduces recurrence rates.

RESUMO

Introduction: Teratoma is a germ cell tumor, deriving from totipotent cells. Teratomas usually occur in gonads and are rarely extra-gonadal. The adrenal location is exceptional. Only few cases of primary adrenal teratomas have been reported in literature, mainly in young patients. Case report: We report the case of a 56-year-old female patient who presented with pyrosis, dyspepsia and abdominal pain that was evolving for 5 months. The abdominal computed tomography revealed a voluminous mass of the right adrenal gland and the hormonal evaluation was normal. The patient underwent an open transperitoneal adrenalectomy and the histopathological examination of the specimen confirmed the diagnosis of mature teratoma. Discussion: Adrenal teratomas are commonly asymptomatic and their diagnosis depends mostly on radiologic findings. Malignant transformation is very rare. Surgical excision is the mainstay of treatment with a good prognosis. Conclusion: Open surgery should always be considered in large and adhering teratoma tumors of the adrenal gland. Some pathologic features and tumorigenesis of adrenal teratomas are not entirely elucidated, thus the importance of larger studies in order to comprehend this pathological entity.
