Perianal mantle cell lymphoma mimicking an external thrombosed hemorrhoid: a case report

INTRODUCTION Malignancies of the anal margin and perianal skin are relatively uncommon, and account for approximately 2% to 3% of all anorectal malignancies. Despite the fact that gastrointestinal presentation of lymphoma is not uncommon, primary localization of mantle cell lymphoma to the perianal region is rare. CASE PRESENTATION We present the case of a 64-year-old Turkish man with a rapid...

Mantle Cell Lymphoma of the Palatine Tonsil: A Rare Case Report

Mantle Cell Lymphoma Mimicking Rectal Carcinoma

Mantle cell lymphoma (MCL) is a mature B-cell non-Hodgkin lymphoma. After the (11;14) translocation was identified as its constant finding in 1992, MCL was recognized as a separate subgroup of non-Hodgkin lymphoma (NHL). In MCL, extranodal involvement may be observed in the bone marrow, the spleen, the liver, and the gastrointestinal system (GIS). Cases of MCL that present with a massive and so...

Skin Manifestations Associated With Mantle Cell Lymphoma: a Case Report

Mantle cell lymphoma (MCL) is a distinct non-Hodgkin's lymphoma type that commonly affects extra nodal sites. The most often affected sites are bone marrow, gastrointestinal tract and Waldeyer's ring, being the skin rarely involved. We report a case of 56 year-old man with MCL, exhibiting multiple large maculopapular skin rashes and skin ulcers. Histopathological examination had not shown direc...

Primary Cutaneous Mantle Cell Lymphoma: A Case Report

Primary cutaneous mantle cell lymphoma (MCL) is a rare cutaneous proliferation of naive pregerminal CD-5 positive B cells in the skin with no extracutaneous involvement. Overexpression of cyclin D1 is pathognomonic of this condition, and surgery and radiation therapy are the most common therapeutic options. In this case, we describe the clinical, histopathological, immunohistochemical, and mole...
