Intrathoracic Manifestation In Rosai Dorfman Disease (RDD): A Case Report With Review Of The Literature

Rosai-Dorfman disease, previously known as sinus histiocytosis with massive lymphadenopathy (SHML) is one of the rare benign idiopathic proliferative diseases of phagocytic histiocytes. Majority of the patients present with painless massive cervical lymphadenopathy but intrathoracic involvement is rarely reported. Here, we report the case of a 57-year-old male with a history of chest pain, shortness of breath and generalized weakness of two-month duration. The diagnosis was formed by core biopsy of the axillary lymph node with typical emperipolesis and Immunohistochemistry markers

T-Cell Rich B-Cell Lymphoma Of The Breast: A Rare Case Report With Emphasis On The Role Of Immunohistochemistry In The Diagnosis

Primary breast lymphoma is one of the rare tumors that commonly presents as a lump with <0.5% incidence rate. It may be misdiagnosed as poorly differentiated carcinoma on routine fine-needle aspiration cytology. With appropriate treatment, this breast malignancy has a relatively better prognosis. Here, we report the case of a mammary T-cell rich B-cell non-Hodgkin lymphoma in a pre-menopausal woman diagnosed by biopsy and later confirmed by immunohistochemistry.
