Sebaceous lymphadenoma is a rare benign salivary gland tumor of uncertain histogenesis. We report such a case in a 37-year-old female presenting with a parotid swelling. Recognition of key histological features will readily allow differentiation of this neoplasm from its benign and malignant mimics. The prognosis is excellent following excision.
Philadelphia chromosome (Ph(1))-positive Chronic Myelogenous Leukemia (CML) in a child below the age of 3 years is extremely rare. We have reported such a case in a 3 year old male child. Peripheral blood smear revealed features of CML and karyotypic study showed (Ph(1)) positivity. Biologic behaviour and prognosis are similar to that of adult-type of CML.
Rhabdoid meningioma is a rare subtype of meningiomas accounting for 1-3% of all intracranial meningiomas and classified as WHO Grade III tumor. It has an aggressive course and needs to be treated by both surgery and radiotherapy. Here we present a rare case of rhabdoid meningioma in a 24 year old lady with complaints of focal seizures, paresis and diplopia. CT & MRI showed a mass attached to dura in left posterosuperior frontoparietal region with peripheral edema. Histopathology showed large tumor cells arranged in sheets, whorls and papillary pattern. The patient was treated by surgery followed by radiation. This is reported to aware the surgical pathologists to keep this subtype as a differential diagnosis while interpreting any meningioma as it has an aggressive course.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
