GLOMUS TUMOR AND GLOMANGIOMA

Glomus tumors are benign tumors derived from the glomus body. The glomus body is a component of the vascular thermoregulatory unit. These tumors are most frequently encountered in early adulthood and are most commonly found on the digits. Glomus tumors are solitary in nature, and the term glomangioma is used when describing the glomuvenous malformation. This usually manifests as a congenital defect in infants and young children and appears to be a multifocal grouping or mass of coalescent glomus tumors.

DESCENT OF THE TESTIS

The early genital ridge on the posterior wall of the coelomic cavity contains the primordial testis and extends from the sixth thoracic to the second sacral segment. At 8 weeks’ gestation, the testis, lying beneath the mesothelium (primitive peritoneum), becomes an elongated, spindle-shaped organ projecting into the coelomic cavity (future abdominal cavity).

DERMATOFIBROMA (SCLEROSING HEMANGIOMA)

Dermatofibromas are among the most common types of benign skin growths. Usually, they occur on the extremities, with a predilection for the legs. There is some debate as to whether this is a true neoplasm or an inflammatory reaction.

BECKER’S NEVUS (SMOOTH MUSCLE HAMARTOMA)

Becker’s nevi most commonly appear on the shoulder or upper limb girdle of prepubescent boys. It is a rather common benign condition that is seen in up to 0.5% of the male population. It is less commonly seen in females. Becker’s nevi are acquired nevi. Most occur before 10 years of age. Becker’s nevus is classified as a smooth muscle hamartoma. It does not contain melanocytic nevus cells and is not considered to be a melanocytic nevus. It was given its name by the dermatologist Samuel Becker, who first described this condition.

ACROCHORDON

Acrochordons are better known by their common name of skin tag or fibroepithelial polyp. They are found universally throughout humankind. Probably every adult has at least one skin tag located somewhere across the surface of his or her skin. Except for a few loose associations with certain syndromes, skin tags have no clinical importance and are often ignored.
