Abstract:
Mantle cell lymphoma (MCL) is a distinct type of non-Hodgkin's lymphoma that commonly affects extranodal sites. The most commonly affected sites are bone marrow, gastrointestinal tract and Waldeyer's ring, however, skin is rarely involved. We reported a 62-year-old Japanese patient with MCL, exhibiting multiple small dome-shaped red nodules and skin ulcers. Histopathological examination demonstrated numerous atypical lymphoid cells in the dermis and subcutis. Immunohistochemically, tumor cells were positive for CD20 (L26), CD5, CD43 and cyclin D1, but negative for CD45RO (UCHL-1), CD3, CD10 and CD23. Our patient showed a significant improvement of skin lesions and lymphadenopathy with a combination chemotherapy. Awareness of skin manifestations of MCL is essential for dermatologists to establish an early diagnosis and perform appropriate treatment.

The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
