Rare benign mixed tumour of the upper lip: A case report

Abstract

BackgroundChondroid syringomas (CS) are rare benign mixed tumours. Clinical differentiation can be misleading due to the silent presentation, with only histopathological findings confirming the diagnosis.Case reportA 23-year-old Caucasian gentleman presented with an eighteen month history of increasing size of his exophytic upper lip mass.The initial clinical impression was thought to be related to the skin. Following a punch biopsy, histopathology confirmed appearance in keeping with part of a chondroid syringoma with subsequent excision of the lesion.DiscussionCS present as a slow-growing, asymptomatic, non-tender, nonulcerated, smooth, firm subcutaneous, or intradermal nodule and can range from 0.5 to 3.0 cm, predominantly occurring in the head and neck region in patients aged above 35 years with a male predication. The most effective diagnostic method is microscopic examination. The gold standard treatment modality is by complete excision with a margin of normal tissue in order to examine the histopathologic features and prevent recurrence.ConclusionCS should be included as a differential diagnosis of facial subcutaneous skin lesions in middle aged male patients. Careful evaluation, with a view of total excision and adequate surgical margin will enable diagnostic confirmation, whilst maintaining the aesthetic and functional unit.

Giant chondroid syringoma on the upper lip: a case report

“…Chondroid syringoma may originate from ectopic tissue of embryological origin that proliferates owing to unidentified factors [4]. The presentation on the lips, soles, and fingers suggests that it may be preceded by trauma [2,4].…”

“…The presentation age is between 20 and 60 years and it is more frequent in men than in women with a ratio of 2:1. The most common location is nose, cheek, upper lip, scalp, forehead, chin, eyelids, ear, and neck; it rarely affects the extremities and genitalia [2]. Since 1959 only about 34 cases have been reported [5].…”

“…Chondroid syringoma generally is located on the face and neck and may have a chronic and asymptomatic course. It is rare, with an incidence of 0.01% to 0.098% of all primary skin tumors [2]. They are solitary tumors, generally less than 3cm in diameter.…”

Benign chondroid syringoma affecting the upper lip: Report of a rare case and review of literature

“…A search through the existing literature was carried out for all the reported cases of CS at various sites which revealed very few cases of CS on the upper lip [Table 1]. [4567891011121314]…”

Laryngeal lipoma: a rare cause of acute intermittent airway obstruction

“…He had a medical history of a right radical nephrectomy for clear cell carcinoma, transitional cell carcinoma of the bladder, a previously excised chondroid syringioma of the face (a rare benign mixed tumour arising from sweat glands), unstable angina and hypercholesterolaemia 8. His medication history included only aspirin and a statin.…”
