Lymphocytoma cutis of the face treated with corticosteroids.

Lymphocytoma cutis refers to a group of skin disorders that are characterized by lymphoproliferation, primarily T and B cell populations. These lesions are also referred to as pseudolymphoma to distinguish these benign lesions from malignant cutaneous lymphomas. The differentiation between pseudolymphoma and lymphomas requires careful histopathological evaluation and may even necessitate immunohistochemistry studies. The presentation of cutaneous Bcell pseudolymphoma (CBPL ) includes a solitary red nodule or plaque in about 90% of patients, however about 10% of patients will present with multifocal diseases. Pruritis, edema and inflammation of the involved area are also common. The skin of the head and neck seems to be affected more than other parts of the body. The mainstay of treatment of CBPL is topical corticosteroids, intralesional injections may also be considered for lesions that do not completely resolve with topical injections.
