A case of non-hallopeau-siemens recessive dystrophic epidermolysis bullosa.

Dystrophic epidermolysis bullosa (DEB) is a rare group of heritable mechanobullous disorders that are characterized by blistering and scarring of the skin and mucosae and these lesions are induced by minor trauma, DEB is also associated with nail dystrophy. DEB can be inherited either in an autosomal recessive or dominant fashion. Regardless of the mode of inheritance, DEB is caused by defects of the ultrastructural entity known as the anchoring fibril, which results in separation of the sublamina densa.

A Case of Aggressive NK/T-cell Lymphoma/Leukemia with Cutaneous Involvement in Adolescence.

NK/T-cell lymphoma (NKTCL) is characterized by the expression of the NK-cell antigen CD56. Non-nasal NK/T-cell lymphomas are subdivided into primary cutaneous and 4 subtypes of secondary cutaneous lymphomas; nasal type, aggressive, blastic (blastoid), and other specific NK-like cell lymphoma. Aggressive NK/T-cell lymphoma/leukemia is a rare leukemic variant of nasal type NKTCL.

A Case of Axillary Adenoid Basal Cell Carcinoma.

Basal cell carcinoma (BCC) is the most common skin cancer with a steadily increasing incidence. Ultraviolet radiation is considered the single most important risk factor for BCC, because the tumor occurs most frequently in sun-exposed areas of the body, with approximately four of five BCCs occurring on the face. BCC occurs infrequently in non-sun-exposed skin.
