Cutaneous Lymphadenoma: A Case Report and Literature Review

Cutaneous lymphadenoma (CL) is an uncommon epithelioid tumor that is usually present on the head and face. It was first described by Santa Cruz and Barr in 1987, as a lymphoepithelial tumor, and was renamed as CL in 1991. Although CL is considered as a benign tumor, there are cases of recurrence after shave excision and metastasis to regional lymph nodes. Correct diagnosis and complete resection are of great importance. Here, we report a typical case of CL and make a comprehensive review of this rare skin tumor.

Cutaneous Lymphadenoma: A Case of Recurrence after Shave Excision

Cutaneous lymphadenoma (CL) is a rare skin tumor supposedly derived from the pilosebaceous unit. Since its description in 1987, fewer than 60 cases have been documented. Herein we report a case of CL presenting as a small nodule on the forehead of a young female. The lesion recurred two years after shave excision of a similar lesion. The histopathological examination revealed interconnected islands, sheets, and trabeculae consisting of two distinct types of cells within a sclerotic stroma, a peripheral rim of palisading basophilic cells, and central epithelial cells with eosinophilic to clear cytoplasm. A dense infiltration with prominent lymphocytes and few plasma cells dominated the stroma and permeated the epithelial nests. This case represents the recurrence of this type of skin tumor after shave excision and thus highlights the importance of complete margin-free excision of such lesions.

Cutaneous lymphadenoma: a rare case and brief review of a diagnostic pitfall

We report a case of cutaneous lymphadenoma on the posterior left ear of a 67-year-old woman. Although it is benign, recognition of cutaneous lymphadenoma is important as it presents a diagnostic pitfall to the unsuspecting dermatologist and general surgical pathologist, who may readily misdiagnose the lesion because it is not only very rare, but also clinically and histologically resembles the far more common and locally destructive basal cell carcinoma.
