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...

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...

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...

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...

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....

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....
