Unusual presentation of skin nodule in a child: a case report of primary cutaneous CD4<sup>+</sup> small/medium T-cell lymphoproliferative disorder and literature review

Primary cutaneous CD4+ small/medium T-cell lymphoproliferative disorder (SMPLPD) is a rare, definite type of cutaneous T-cell lymphoma (CTCL) that accounts for 6% of all primary CTCLs. Characteristically, this lymphoproliferative disorder presents as a solitary nodule, plaque, or tumor, generally on the face, neck, or upper trunk. We report a case of SMPLPD presenting as a facial nodule in a 6-year-old Saudi girl. The patient was successfully treated with complete excision and showed full resolution, with no recurrence at 6-month follow-up.
