Viral-Associated Trichodysplasia of Immunosuppression

Viral-associated trichodysplasia of immunosuppression is an increasingly recognized entity characterized by follicular-based papules, primarily in the central part of the face, that produce variable degrees of alopecia and dysmorphic features. It has been primarily described in transplant recipients but has recently been recognized in patients receiving chemotherapy for leukemia and lymphoma. It is associated with distinctive histologic features such as dilated anagen hair follicles, absent hair papillae, and abrupt cornification of the inner root sheath.
