Abstract

Mixed tumour of the skin or chondroid syringoma (CS) is a rare and mostly benign neoplasm of the sweat glands. Although CS is frequently located on varied parts of the head and neck region, the lower lip is a rarely reported site. The present report describes a case of CS of the lower lip in a 58‑year‑old male as an expository case to further emphasise the need for proper diagnosis, appropriate treatment and prognostic evaluation. The patient presented with a round, non‑tender, slightly hard and mobile mass beneath the mucocutaneous junction of his left lateral side of the lower lip. Radiology revealed a mass measuring 11x11x7 mm3 in size at a depth of ~2 mm. Furthermore, magnetic resonance T1‑ and T2‑weighted images showed slightly low and high signal intensities, respectively. A provisional diagnosis of benign tumour of the lower lip was made, and surgical excision biopsy taken under local anaesthesia, while considering the patient's cosmetic appearance. Histopathology demonstrated features akin to apocrine gland, chondroid and myxoid stroma consistent with the diagnosis of benign CS. No evidence of recurrence or satellites were recorded after a follow‑up of nearly 2 years. Although rare, a high index of suspicion for CS among other cutaneous adnexal tumours of the lower lip is necessary. In addition, interprofessional collaboration in the management of such oral tumours could enhance patient satisfaction amid prevailing intraoral and aesthetic concerns.
