Cutaneous lymphadenoma in a young Saudi female: a case report.

Background: Cutaneous lymphadenoma (CL) is a rare benign epithelial neoplasm. It presents as skin-colored nodule in the head and neck area. CL is an uncommon condition with less than 60 cases reported in the literature and very rare occurrence in the Asian population; it has never been previously reported in the Arabian gulf countries. We report the first case of CL in a young Saudi female.

Case Description: A 28-year-old Saudi female presented with an asymptomatic skin lesion on her forehead that first appeared eight years ago. Physical examination showed a 3 mm × 3.4 mm solitary, nontender, firm, skin-colored to pink nodule with overlying telangiectasia. A biopsy was taken, and histopathology findings revealed epithelial nests of uniform, small basaloid cells with some peripheral palisading; a fibrotic stroma; and Lympho-histiocytic inflammatory infiltrates. No retraction artifacts, atypia or necrosis were observed. These findings are consistent with CL. The lesion was fully excised by skin punch biopsy without any residual tumor. No recurrence was observed after 1 year follow-up.

Conclusions: CL presents a diagnostic pitfall, and many dermatologists fail to recognize it in the initial clinical impression. Moreover, although CL is a rare and benign tumor, it must be in the differential diagnosis of any asymptomatic skin nodule in the head and neck area.
