Full Answer

Lymphomas that spread to the skin from other sites of the body are not skin lymphomas. All skin lymphomas are non-Hodgkin lymphomas and have either a T-cell or B-cell origin, although T-cell skin lymphomas are the most common, explains the American Cancer Society.

Almost half of all skin lymphomas are mycosis fungoides. This is a slowly growing cancer that initially presents as a patchy, scaly skin lesion, making it difficult to diagnose. It can eventually develop into a solid, raised tumor and spread to other organs, such as the liver, according to the American Cancer Society.

Other T-cell skin lymphomas include Sezary syndrome, which can develop in patients with mycosis fungoides, primary cutaneous anaplastic large cell lymphoma, lymphomatoid papulosis, subcutaneous panniculitis-like T-cell lymphoma, and a group of less common lymphomas, explains the American Cancer Society.

The most common B-cell skin lymphoma is primary cutaneous follicle-center lymphoma. This cancer grows slowly and looks like a group of red pimples, plaques or nodules, which most frequently appear on the scalp, shoulders and torso, according to the American Cancer Society.
