RESUMO

Solitary plasmacytoma of the breast is an extremely rare neoplastic entity characterized by the localized proliferation of neoplastic plasma cells within the breast tissue that requires careful consideration due to its clinical and radiological resemblance to more common breast malignancies. While plasmacytomas are typically associated with multiple myeloma (MM), primary involvement of the breast as a solitary lesion is exceptionally rare. In this report, we present a case of solitary plasmacytoma of the breast in a 55-year-old female patient who presented with a palpable breast mass and no signs of systemic multiple myeloma. Our objective is to discuss the clinical presentation, radiological features, and histopathological findings and highlight the importance of comprehensive diagnostic workup and management planning for solitary plasmacytomas of the breast.

RESUMO

Non-seminomatous germ cell tumors with structural components from all three cellular lineages are called teratomas. We report a rare case of a primary right adrenal teratoma in a postmenopausal female, presenting with abdominal pain. Ultrasound revealed a complex cystic shadow in the perihepatic region superior to the upper pole of the right kidney, which was suggestive of a complex supra-renal space-sequence-occupying lesion. Computerized tomography revealed a large-sized mature single multilobulated complex cystic lesion in the right hypochondrial lumbar region arising from the right adrenal gland. A right-sided transperitoneal adrenalectomy was performed. The resected mass (18 × 13 × 10 cm) was well encapsulated. Cut surfaces showed cystic mass filled with necrotic gray-white pultaceous material, along with a solid white gelatinous area. Microscopic sections showed a tumor which displayed differentiation along various tissue lineages. After immunohistochemical examinations, the tumor was confirmed to be a mature cystic teratoma. Mature teratomas show a good prognosis, and surgical resection and follow-up remain the standard approach.

RESUMO

CD44 + /CD24 - phenotype has been associated with stem cell-like characteristics with enhanced invasive properties, radiation resistance, and with distinct genetic profiles suggesting a correlation to adverse prognosis in western literature. The aim of this study was to study CD44 + /CD24 - phenotype as an adverse prognostic marker in Indian breast cancer patients. N = 61 breast cancer patients included in a tertiary care facility in India were evaluated for receptor studies (estrogen receptor ER, progesterone receptor PR, Herceptin antibody Her2 neu receptor, CD44 & CD24 stem cell markers). CD44 + /CD24 - phenotype was statistically related to adverse factors like estrogen and progesterone receptors non-expression, her 2 neu expression, and triple-negative breast cancer. Of the 39 patients with ER-ve status, 33 (84.6%) were found to have CD44 + /CD24 - phenotype and 82.5% of all the CD 44 + /CD24 - patients were ER negative (p = 0.001). Thirty-four (75.5%) of the PR-ve patients showed the CD44 + /CD24 - phenotype, and of all the CD 44 + /CD24 - patients, 85% of were PR negative (p = 0.006). Thirty-six (75%) of Her-2-Neu + ve were CD44 + /CD24 - . Approximately 90% of the Her 2 Neu patients expressed CD44 + /CD24 - and 76.9% of all the triple-negative patients were found to be CD44 + /CD24 - expression (p = 0.001). CD44 + /CD24 - had a significant association with adverse prognostic factors like stage of disease, hormonal receptor status, and molecular subtypes in Indian breast cancer patients like the Western data.

RESUMO

OBJECTIVE: To study the total goitre rate (TGR), urinary iodine concentration (UIC) and salt iodine content among schoolchildren in a previously endemic area for severe iodine deficiency disorder (IDD). DESIGN: Cross-sectional epidemiological study. SETTING: The study was carried out in the Gonda district (sub-Himalayan region) of North India. PARTICIPANTS: Nine hundred and seventy-seven schoolchildren (6-12 years) were studied for parameters such as height, weight, UIC and salt iodine content. Thyroid volume (TV) was measured by ultrasonography to estimate TGR. RESULTS: The overall TGR in the study population was 2·8 % (95 % CI 1·8, 3·8). No significant difference in TGR was observed between boys and girls (3·5 % v. 1·9 %, P = 0·2). There was a non-significant trend of increasing TGR with age (P = 0·05). Median UIC was 157·1 µg/l (interquartile range: 94·5-244·9). At the time of the study, 97 % of salt sample were iodised and nearly 86 % of salt samples had iodine content higher than or equal to 15 part per million. Overall, TGR was significantly lower (2·8 % v. 31·0 %, P < 0·001), and median UIC was significantly higher (157·1 v. 100·0 µg/l, P < 0·05) than that reported in the same area in 2009. CONCLUSIONS: A marked improvement was seen in overall iodine nutrition in the Gonda district after three and a half decades of Universal Salt Iodisation (USI). To sustainably control IDD, USI and other programmes, such as health education, must be continuously implemented along with putting mechanisms to monitor the programme at regular intervals in place.

RESUMO

Large adrenal tumors pose varied challenges to surgeons in terms of diagnosis, planning surgical approach, and also intra-operative difficulties in resection. The aim of this study is to discuss challenges in the management of large and difficult adrenal lesions. A retrospective analysis was done on data of all patients with large adrenal lesions/paragangliomas managed from 1 June 2016 to 30 August 2018. Forty-eight patients with adrenal lesions underwent treatment in 2 years duration. Pain in the abdomen was the most common presentation. Mean age was 34.4 years (range 2-60), female to male (23:25) and right to left side to bilateral tumor 30:16:2. Thirty-one (64.6%) patients had large adrenal masses (size > 6 cm). Surgical approaches included open transperitoneal adrenalectomy (n = 20) and laparoscopic transperitoneal (n = 9 and 2 others had conversion to open procedure). Challenges faced are described in the table below: [Table: see text] There were no major peri-operative morbidities, but two patients died in perioperative period. Large adrenal tumors pose a challenge in surgical planning, approach, and resection and need careful planning and multidisciplinary team approach to have the best outcomes.

RESUMO

INTRODUCTION: Oral cancer is a sixth commonly occurring cancer globally. The use of tobacco and alcohol consumption are being considered as the major risk factors for oral cancer. The metabolic profiling of tissue specimens for developing carcinogenic perturbations will allow better prognosis. OBJECTIVES: To profile and generate precise 1H HRMAS NMR spectral and quantitative statistical models of oral squamous cell carcinoma (OSCC) in tissue specimens including tumor, bed, margin and facial muscles. To apply the model in blinded prediction of malignancy among oral and neck tissues in an unknown set of patients suffering from OSCC along with neck invasion. METHODS: Statistical models of 1H HRMAS NMR spectral data on 180 tissues comprising tumor, margin and bed from 43 OSCC patients were performed. The combined metabolites, lipids spectral intensity and concentration-based malignancy prediction models were proposed. Further, 64 tissue specimens from twelve patients, including neck invasions, were tested for malignancy in a blinded manner. RESULTS: Forty-eight metabolites including lipids have been quantified in tumor and adjacent tissues. All metabolites other than lipids were found to be upregulated in malignant tissues except for ambiguous glucose. All of three prediction models have successfully identified malignancy status among blinded set of 64 tissues from 12 OSCC patients with an accuracy of above 90%. CONCLUSION: The efficiency of the models in malignancy prediction based on tumor induced metabolic perturbations supported by histopathological validation may revolutionize the OSCC assessment. Further, the results may enable machine learning to trace tumor induced altered metabolic pathways for better pattern recognition. Thus, it complements the newly developed REIMS-MS iKnife real time precession during surgery.

RESUMO

Non-traumatic splenic rupture has been described in the medical literature as a clinical entity with grave consequences, if diagnosis and subsequent treatment are delayed. Various pathological reasons implicated in non-traumatic spontaneous splenic rupture have been described in literature ranging from infection, malignancy, metabolic disorders as well as haematological malignancies. This case reports a 30-year-old man who presented in the emergency department with complaints of fever and a sudden-onset abdominal pain with no history of trauma. At hospital admission, abdominal tenderness with splenomegaly was present with free fluid in abdomen. Haematological investigations established the coinfection of Plasmodium falciparum and Plasmodium vivax. Radiological investigations revealed splenic laceration with moderate haemoperitoneum. The patient was managed conservatively with strict vital monitoring. Later on, elective splenectomy was performed. The authors report only the second case in literature with coinfection of plasmodium species presenting with haemoperitoneum.
