ABSTRACT
BACKGROUND: The pigmented or melanotic variant of choroid plexus carcinoma is very rarely encountered. CASE REPORT: We report herein a case of melanotic or pigmented choroid plexus carcinoma in the posterior fossa of an 11-year-old female. CONCLUSIONS: A histopathological study supported by immunohistochemistry helped the authors to diagnose this rare entity. How to differentiate this tumor from pigmented papillary medulloblastoma, cerebellar papillary ependymoma, and metastatic malignant melanoma is discussed.
ABSTRACT
Post kala-azar dermal leishmaniasis (PKDL) is a rare disease. This is a solitary case report from Orissa, India. We describe a case of PKDL in a 55-year-old male who presented with multiple nodular lesions over face, trunk, and extremities. The patient had been to an endemic area of kala-azar and had a previous history of leishmaniasis. Fine needle aspiration cytology samples from skin nodules revealed Leishmania amastigotes.

Malignant peripheral nerve sheath tumor with rhabdomyoblastic differentiation, malignant triton tumor, has a rare incidence. We report such a case in a 40-year-old male who presented with a mass over the buttock. He was a previously diagnosed case of neurofibroma in the same area. Histomorphology supported by immunostaining with S-100 protein confirmed the diagnosis. Malignant triton tumor has a poor prognosis owing to its aggressive biological behavior. The fact that the presence of this tumor in the buttock region is extremely rare has prompted the authors to report this case.
