Chondrosarcoma of distal phalanx with imaging study; a report of rare case with review of the literature

Chondrosarcoma of distal phalanx is extremely rare and to our best knowledge there was only one case having magnetic resonance ( MR ) imaging study. We report a case of 56-year-old woman developing chondrosarcoma of distal phalanx of the left ring finger. The radiographic and imaging studies highly suggested chondrosarcoma and amputation of distal...Continue reading →

Primary sinonasal mucosal melanoma with CD138 expressed plasmacytoid cells: a case report and review of literature

Primary sinonasal mucosal melanoma is a rare neoplasm. Like in other sites of malignant melanoma, the histopathology is variable and when lacking of melanin pigment, particularly in small biopsy specimen mimicks many neoplasms. Immunohistochemical staining plays an important role. Many immunomarkers, including S-100, HMB-45 and Melan-A should be...Continue reading →

Sclerosing Polycystic Adenosis of the Parotid Gland: Report of A Case with Multifocality

Sclerosing polycystic adenosis (SPA) is a rare tumor-like lesion of the salivary gland that bears a histomorphological resemblance to fibrocystic disease and sclerosing adenosis of the breast. The lesion is widely considered to be a pseudoneoplastic inflammatory process. However, foci of epithelial dysplasia and carcinoma in situ can occur in the...Continue reading →

Primary Testicular NK/T-cell Lymphoma presented as testicular abscess: A Case Report and Literature Review of 33 cases

Primary testicular NK/T-cell lymphoma is rare. We report a 61-year-old Thai man who presented with right testicular abscess clinically but tissue obtained from incision and drainage was proven to be NK/T-cell lymphoma. The lymphoma cells were small to medium in size and showed angiocentricity with associated necrosis. The lymphoma cells were CD3+...Continue reading →

Traumatic asphyxial death from two-wheel ‘walking behind’ tractor

A 41-year-old man was found suspended 15 cm above the floor, hanging from the long handle-bars of a twowheel ‘walking behind’ tractor. The floor was downward sloping and muddy, which caused the tractor to dig into the floor, raising the long handle bars under the arms of the victim, and pushing him against a pillar....Continue reading →

Non-functioning adrenal cortical adenoma arising in adrenohepatic fusion, mimicking hepatocellular carcinoma – a case report

Adrenal cortical adenoma arising in adrenohepatic fusion is an exceedingly rare occurrence. It can potentially be misinterpreted as hepatocellular carcinoma as they share radiologic and histologic similarities. We report an incidental subcapsular adrenal cortical adenoma arising in adrenohepatic fusion tissue in segment 7 of the liver...Continue reading →

Mantle cell lymphoma presenting as multiple lymphomatous polyposis of colon: A case report.

Mantle cell lymphoma is a clinically aggressive lymphoma with a poor prognosis. Secondary involvement of gastrointestinal tract by this neoplasm is not uncommon but the primary involvement with distinguished multiple lymphomatous polyposis is unusual. We report a case of mantle cell lymphoma presenting as multiple lymphomatous...Continue reading →

Sudden Death from Retroperitoneal Hemorrhage Due to Necrotizing Pancreatitis

We report a case of sudden death from retroperitoneal hemorrhage in 73-year-old male due to rupture of peri-pancreatic artery in acute necrotizing pancreatitis. This appears to be the first case report of sudden death from retroperitoneal hemorrhage due to pancreatitis. The rupture site was not identifiable by gross-exami- nation but it was confirmed...Continue reading →

Neuroendocrine Tumor of the Gallbladder with Hepatic Metastases: A Case Report

A 68-year-old woman presented with hepatic metastasis. She had been performed cholecystectomy at a provincial hospital for symptomatic gallstones and was diagnosed as poorly differentiated adenocarcinoma of the gallbladder. The follow-up hepatic segmentectomy revealed a malignant small round tumor composed of nests of cells containing small nuclei...Continue reading →

CD43 Expression in Malignant Melanoma: A Diagnostic Pitfall

CD43 is commonly concerned as a marker for hematopoietic cells and, at times, a preferential T-cell marker. However, a number of non-hematologic cancers, mostly carcinoma, can express CD43. Recently, a case of malignant melanoma mimicking malignant lymphoma by cytomorphology was reported to express CD43 as well as melanoma markers but the other hematologic...Continue reading →

Bursitis with pseudosarcomatous fibroblastic proliferation; a case report

Pseudosarcomatous fibroblastic proliferation (PSFP) is a quite common lesion found in various locations in- cluding soft tissue, bone and other organs and often raises a difficult differential diagnosis with malignancy. However, PSFP has not been described in tissue related to bursitis. We report a case of 31-year-old male who developed a cystic...Continue reading →

Incomplete pentalogy of Cantrell: a case report

Pentalogy of Cantrell is a rare congenital syndrome characterized by defects involving the supra-umbilical abdominal wall, lower sternum, anterior diaphragm, pericardium, and the intra-cardiac anomalies. The ensuing congenital heart disease is a source of major morbidity. The full spectrum of the syndrome is rare while incomplete expression of the...Continue reading →

Primary central nervous system lymphoma presenting with panhypopituitarism and diabetes insipidus

Lymphoma involving the hypothalamus is very rare. We present a case of a 48-year-old man with primary central nervous system lymphoma (PCNSL) presenting with hypothalamic and pituitary stalk lesions with frontal masses, causing diabetes insipidus and panhypopituitarism. Brain MRI with gadolinium enhancement demonstrated vivid enhancing hypothalamic and...Continue reading →

Disseminated Tuberculosis in a Mother with Diffuse Large B-cell Lymphoma resulting in Placental and Inferred Congenital Tuberculosis: An Autopsy Case Report

Tuberculosis of the placenta is a rare condition which mainly occurs in the immunosuppressed individuals especially in acquired immune deficiency syndrome (AIDS) and hematologic malignancy9. Tuberculosis can spread to the fetus via hematogenous or cervicovaginal route and result in congenital tuberculosis....Continue reading →

Pulmonary alveolar proteinosis coexisting with homozygous hemoglobin E

Pulmonary alveolar proteinosis (PAP) is an uncommon lung disorder of obscure and possibly diverse causes characterized by abnormal accumulation of lipoproteinaceous surfactant material in alveoli. The prevalence of acquired PAP has been estimated to be 0.37 per 100,000 populations. We present a case of PAP coexisting in homozygous hemoglobin (Hb) E....Continue reading →
