Serpiginous ganglion cyst of the foot mimicking cutaneous larva migrans.
A patient had a serpiginous lesion on the foot that turned out to be a ganglion cyst. This lesion is more common on the hands. On the lower extremity, ganglion cysts tend to have a misleading clinical appearance. Histologic examination shows pseudocysts formed by mucoid degeneration of collagen structures. The pathogenesis is unclear. Many ganglions are asymptomatic, but pain occurs in 50% of cases. Management of symptomatic lesions is surgical excision. Recurrence is possible.
Basal cell carcinoma of the earlobe after auricular acupuncture.
The genesis of familial and sporadic basal cell carcinomas involves activation of the Sonic hedgehog signal transduction pathway. Other known factors for the development of basal cell carcinoma are ultraviolet exposure, X-rays, race, age, gender and decreased DNA repair capacity. We here report the case of a right earlobe sporadic basal cell carcinoma in a 65-year-old woman. This case is unusual because of its earlobe localization and its association with multiple auricular acupuncture treatments. This observation suggests a connection between local traumas, which occur in the course of acupuncture treatment and ear piercing, and the genesis of basal cell carcinoma. The incidence of minor adverse events associated with acupuncture is high, but serious events are uncommon. Acupuncture is not known to date for promoting the development of tumors. This connection remains to be elucidated.
