Carbimazole-induced atypia – A mimicker of malignancy in fine-needle aspiration cytology

A 20-year-old female presented with complaints of thyroid swelling and showed signs and symptoms of thyrotoxicosis and fine-needle aspiration cytology (FNAC) was requested by the surgeon. On examination of FNAC smear, it showed thyroid follicular cells with atypical features like bizarre giant cells, pseudo nuclear inclusions, and mitotic figure. Correlation between clinical history and cytomorphologic features was done and it was reported as atypical changes in thyroid probably due to carbimazole-induced changes. It helped the patient, as radical surgery and its untoward complications were avoided.

Boon that Resolves Microscopic Puzzle

Introduction: Immunohistochemistry plays a major role to confirm the accurate diagnosis of non-Hodgkin lymphoma B cell type -Tonsillar fossa. Case Presentation: A 65 year old male presented with blocking sensation in the throat, dysphagia and loss of appetite with loss of weight since 2 months. Video laryngoscopic examination revealed a growth in the right tonsil. Contrast enhanced CT neck showed well defined mass in the tonsillar fossa with multiple enlarged lymph nodes in right submandibular and para tracheal region. Biopsy showed predominantly necrotic tonsillar tissue with lymphoid cells showing angiocentric distribution along with few bizarre cells. The differential diagnosis was Lymphoma and Poorly differentiated carcinoma. Immunohistochemistry was done which showed the neoplastic cells positive for CD 20 and negative for CD 3 and cytokeratin. A diagnosis of non-Hodgkin lymphoma B cell type-Right tonsillar fossa was made. The patient was referred to medical oncology for chemotherapy. Conclusion: We present this case to highlight the role of immunohistochemistry to arrive at the accurate diagnosis and management of the patient.

Clinicopathological profile of hepatoblastoma: An experience from a tertiary care center in India

Background: Hepatoblastoma is the most common primary hepatic malignancy in the pediatric population. Advances in pathological evaluation, imaging, risk stratification, neo-adjuvant chemotherapy, and surgery including transplantation have improved survival of these children in the western countries. However, a successful outcome in developing countries such as India with limited resources poses great challenges to the clinician and the family. Histology plays a major role in determining the prognosis of these patients. Methods: A retrospective study was done on 10 children diagnosed with hepatoblastoma between January 2010 and December 2015 in our institution. Clinical, laboratory, radiological, histopathological diagnoses, treatment, and outcome data were collected and analyzed. Results: The median age of these children at diagnosis was 11 months, and only 1 child was premature at birth. Most children were presented with abdominal distension. One child had lung metastasis at presentation. Elevated alpha fetoprotein levels were present in 90% of the children. The histological types were fetal, embryonal, macrotrabecular, and mixed epithelial-mesenchymal types. SIOPEL risk stratification was done, which showed 40% of the children to be of high risk. Three children had PRETEXT 1, 2, and 4, respectively. Conclusion: Our study is significant with respect to the information on PRETEXT staging, risk status, and histological favorability. In developing countries with limited resources and low-socioeconomic status, it is important to have a multidisciplinary team approach and tailor treatment to manage these patients effectively and improve the overall survival.

Isolated Duodenal Metastasis of Hepatocellular Carcinoma: A Rare Presentation.

Hematogenous metastasis to the duodenum from any primary tumor is rare. Hepatocellular carcinoma (HCC) frequently metastasizes to lung and regional lymph nodes. Involvement of small intestines by HCC is mostly via direct invasion of the contiguous neoplasm. We report a case of isolated noncontiguous duodenal metastasis of HCC because of its rarity.

Extramedullary relapse of acute lymphoblastic leukemia in breast: A rare presentation.

Unusual sites of relapses following allogenic hematopoietic stem cell transplantation (HSCT) for acute lymphoblastic leukemia (ALL) are rarely reported. Our report describes a thirty-two-year old female, who developed extramedullary (EM) breast relapse after allogenic HSCT for pre B cell Philadelphia chromosome negative ALL. She had no evidence of leukemia in her marrow demonstrating 100% full donor chimerism, while she had ALL relapse in her breast.

Fatty acid oxidation disorder as a cause of sudden infant death syndrome (SIDS)--a case report.

Although the cause of sudden infant death syndrome (SIDS) remains unknown, extensive studies over the last 10 years have begun to shed some light on this family tragedy. 5% of all cases of SIDS are caused by fatty acid oxidation disorders. We report a case of fatty acid oxidation disorder causing SIDS.

Bilateral renal papillary necrosis due to Candida infection in a diabetic patient presenting as anuria.

A 38 years insulin-dependent diabetic male, with nephropathy on antituberculous treatment presented with painless frank hematuria followed by anuria for a day which was associated with fever. Ultrasonogram of the abdomen showed bilateral hydroureteronephrosis. Necrotic papillae were retrieved after ureteroscopy which on histopathological examination and culture showed Candida albicans. This was successfully treated with fluconazole and ureteroscopic removal of necrotic papillae.
