=========================================================================

● See also Lymphoma chapter
● Equal incidence of B and T cell disorders (noncutaneous lymphomas have B cell predominance)
● May be primary to skin or part of systemic disease
● Common primary cutaneous lymphomas are: T cell - mycosis fungoides; B cell - diffuse large B cell lymphoma, extranodal marginal zone lymphoma, follicular lymphoma
Note: lymphocytes in skin are significant, since not usually present, although may be due to dermatoses

Classification clues
=========================================================================

Angiocentric: lymphomatoid granulomatosis, nasal type NK/T cell lymphoma
Dermal involvement: blastic NK cell lymphoma, CD30+/- large T cell lymphoma, diffuse large B cell lymphoma, follicular center cell lymphoma, granulomatous slack skin disease, inflammatory pseudotumor, lymphoid hyperplasia, lymphomatoid papulosis, marginal zone lymphoma, plasmacytoma, pleomorphic small/medium-sized T cell lymphoma
Dermal-superficial: SÚzary syndrome
Epidermotropic: adult T cell leukemia / lymphoma, mycosis fungoides, mycosis fungoides associated follicular mucinosis, pagetoid reticulosis
Intravascular: intravascular large B cell lymphoma
Subcutaneous: subcutaneous panniculitis-like T cell lymphoma

Micro description
=========================================================================

B cell lymphomas: triangular architecture with base in subcutis, compact and nodular infiltrates with perivascular cuffing; epidermis not involved
T cell lymphomas: heterogenous; may have epidermal involvement; may have large reactive component mixed with tumor cells
