Auricular pseudocysts (APs) are benign intercartilaginous cysts at the auricle. Various therapeutic options have been used to treat APs, but they frequently recur in usual clinical practice. Here, we report a case of AP successfully treated using a silicon cast. A 65-year-old male presented with a cyst on his right auricle. Although a local injection of steroid was administered, the cyst had recurred. A dental silicon cast was applied after removal of the contents of the cyst by suction. There was no recurrence of the cyst 6 years after that treatment. Dental silicon casts are a novel technique for an appropriate fixation over auricles in the treatment of APs and had an effective therapeutic result in our case.
Scrofuloderma is one of the cutaneous manifestations of tuberculosis and usually occurs when underlying tuberculosis such as lymphadenitis directly involves the skin. However, the diagnosis of scrofuloderma without other apparent clinical manifestations of tuberculosis is sometimes challenging. A 27-year-old male from Bangladesh presented with a dome-shaped tumor on his right clavicle. MRI showed a high-density area that expanded from the lymph nodes between the internal jugular vein and the common carotid artery into the tumor on his right clavicle. Bacterial examinations of cultures from the tumor detected <i>Mycobacterium tuberculosis</i>. Further examinations for pulmonary tuberculosis including chest X-ray and computed tomography did not detect any lesions suggestive of pulmonary tuberculosis. From those examinations, the diagnosis of scrofuloderma was made. We emphasize the importance of recognizing a variety of clinical manifestations of tuberculosis including scrofuloderma due to the recent increase of immigrants from developing countries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
