In terms of a differential diagnosis, a skin biopsy was performed with polymorphic light eruption, cutaneous sarcoidosis, cutaneous lupus erythematosus, discoid lupus erythematosus, lupus tumidus, and lymphocytoma cutis
Differentials to keep in mind when evaluating a case of PCALCL are B-cell lymphoma, leukemia cutis, lymphocytoma cutis
, LyP, and other reactive conditions such as arthropod bites, drug eruptions, and viral infections.
Based on the clinical features and aforesaid investigations, the differential diagnoses of nodular/histoid leprosy, reticulohistiocytosis, subcutaneous sarcoidosis, cutaneous localised leishmaniasis, lymphocytoma cutis
, mycosis fungoides and post kala azar dermal Leishmaniasis were considered.
Differential diagnoses of ALHE include granuloma faciale, persistent insect bite reaction, injection site granuloma, cutaneous lymphoma, cavernous hemangioma, pyogenic granuloma, angiomatous lymphoid hamartoma, pseudolymphoma (lymphocytic infiltrate of Jessner, lymphocytoma cutis
), sarcoidosis and bacillary angiomatosis.
Borrelia burgdorferi associated lymphocytoma cutis
: clinicopathologic, immunophenotypic, and molecular study of 106 cases.
Some of them include Hansen's disease- tuberculoid pole, sarcoidosis, lupus vulgaris, chronic cutaneous lupus erythematosus (tumid LE and LE profundus), granuloma faciale and pseudolymphoma (cutaneous lymphoid hyperplasia or lymphocytoma cutis
and Jessner's lymphocytic infiltration of skin).
