Glomus Tumor and Glomangioma: Symptoms, Histology, Causes and Treatment
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.

Testis Descent: How the Testis Descends into the Scrotum and Causes of Cryptorchidism
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): Clinical Features, Histology, Causes and Treatment
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: Symptoms, Causes, Diagnosis and Treatment
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 (Skin Tags): Causes, Clinical Features & Treatment
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.
