- Abstract
Primary cutaneous mucinous carcinoma (PCMC) is a rare low-grade malignant neoplasm derived from the sweat glands. Local recurrence of PCMC occurs frequently, but these lesions rarely metastasize. Due to the absence of classical demographic and clinical characteristics, PCMCs masquerade as sebaceous cyst, lipoma, pilomatrixoma, chalazion, or squamous cell carcinoma. This misdiagnosis frequently leads to incomplete surgical excision which necessitates further surgical therapy for a curative intent. We present a case of PCMC in a 45-year-old woman which presented as a slow- growing and symptomless nodule in the scalp. After clinical evaluation, the patient had a typical surgical excision for a benign-looking lesion. Histological evaluation of the specimen confirmed a localized PCMC in the scalp with involved surgical margins. A thorough oncological assessment by PET-CT scan and radionuclide scintigraphy was performed. Later, a wide local excision using a gamma probe for intra-operative radionuclide localization of the tumor area and sentinel lymph nodes was done. The patient did not have any regional or distant metastases and remained stable at the time of reporting this case. • A short-term result of the management of a rare case of PCMC in the scalp. • A vigilant approach is essential to differentiate PCMC from benign cystic or solid cutaneous lesions. • Upon establishing histology, a complete surgical removal along with free resection margins is required. • The scarcity of clinical data of PCMC demands a careful follow up with clinical examination and imaging.
