Tropical ulcer is a persistent and sluggish ulcerative process with a dominant localization on the skin in the ankle joint area and, less often, the lower third of the leg, which occurs more often in children, young and middle-aged men living in tropical and subtropical climates. As synonyms, tropical ulcer is sometimes called phagedenetic, scabby, jungle, Madagascar, etc.

Tropical sprue is an acquired disease, probably of infectious etiology, characterized by malabsorption and megaloblastic anemia. The diagnosis is established clinically and by small intestinal biopsy. Treatment of tropical sprue involves the use of tetracycline and folic acid for 6 months.

Mycotic skin lesions are a very significant practical problem, both because of their extreme prevalence and their known contagiousness. This is even more true for tropical dermatomycoses, which, like all tropical pathology, can be divided into tropical mycoses proper

Trophic ulcers have characteristic symptoms. They are manifested by the appearance of a long-term non-healing wound on the skin. Symptoms depend on the etiology of the disease against which the trophic ulcer arose.

Trophic ulcers in osteomyelitis are a variant of post-traumatic ulcers. They represent a deep defect of the skin and soft tissues, etiologically associated with a focus of purulent bone destruction. The anamnesis of such patients usually includes data on bone fractures, bone operations. In some patients, ulcers occur against the background of chronic hematogenous osteomyelitis.

A congenital anomaly in the form of skull deformation, in which the head of infants is abnormally shaped and the skull appears triangular, is defined as trigonocephaly.

Tricuspid stenosis is a narrowing of the opening of the tricuspid valve, which obstructs blood flow from the right atrium to the right ventricle. Almost all cases result from rheumatic fever. Symptoms of tricuspid stenosis include a fluttering discomfort in the neck, fatigue, cold skin, and discomfort in the right upper quadrant of the abdomen.

Ebstein's anomaly (tricuspid valve anomaly) is a congenital pathology of the tricuspid valve, characterized by the displacement of the cusps (usually both the septal and posterior) into the cavity of the right ventricle, which leads to the formation of an atrialized part of the right ventricle. As a result of the displacement of the tricuspid valve cusps, the cavity of the right ventricle is divided into two parts.

Most often, hair is plucked from the head, eyebrows, eyelashes, limbs, and pubis. Some patients eat their hair (trichotillophagia). The patchy areas without hair may become noticeable to others - this forces them to wear a wig or resort to intensive measures to disguise it. After plucking, patients do not feel satisfaction, but rather are concerned about the defect in their appearance or experience dissatisfaction due to the inability to control their actions.
