A typical place of localization of chondroma is the cartilaginous tissue of the auricle, which rarely develops and most often in people at a young age. Existing treatment methods are effective and widespread, however, any injury to the tumor accelerates its growth. Therefore, significant development of chondromas is observed after a trial excision or incomplete removal. Cryosurgical treatment refers to gentle, less traumatic methods. Тhe authors describe a case from practice: removal of the chondroma of the outer ear using a СAO-2 cryoapparatus with an individual polyethylene cap, which allows for accelerating and simplifying the process of thawing and re of the instrument. This intervention is outpatient and does not require special preparation. Taking into account the undesirable complications after cryotherapy (swelling, pain due to increased tissue turgor, local deterioration of blood circulation) on the one hand, and taking into account the antitoxic, calming, relaxing, and analgesic effect of magnesium on the body as a whole, the authors used balneotherapy in the form of a course of applications with a natural balneological agent with a high content of magnesium chloride on the zone of cryotherapy, as well as its drinking course consumption. The observation showed that the intervention using a cryoapplicator is a gentle method, slightly damaging the surrounding tissues, minimizing the possibility of intraoperative bleeding, allowing to accelerate the operation process and healing time, and, accordingly, reducing the patient's incapacity for work. Applying the results in clinical practice will significantly reduce the likelihood of deformation of the outer ear and maintain its primary functions.

The article contains information on the problem of the combined course of HIV infection and leishmaniasis: a number of statistical and overview data in the world. It also presents a brief description of known cases of HIV patients with leishmaniasis in the Russian Federation. In all cases the diagnostics of leishmaniasis was difficult due to the lack of alertness of physicians to this illness, as well as poor knowledge of epidemiological situation of leishmaniasis. All patients with visceral leishmaniasis but one caught it during their stay in Crimea. Cutaneous leishmaniasis was described in HIV infection in the Russian Federation for the second time and is associated with the patient's residence in the Chechen Republic.
