Diseases of the skin and subcutaneous tissue (dermatology)

Barré-Masson glomus angioma (glomus tumor): causes, symptoms, diagnosis, treatment

Glomus angioma of Barre-Masson (syn.: Barre-Masson tumor, glomus tumor, angioneuroma, myoarterial glomus tumor) is a benign tumor of the organoid type, developing from the walls of the Suquet-Goyer canal, which is a functional part of the glomerular arteriovenous anastomosis.

Hemangiopericytoma: causes, symptoms, diagnosis, treatment

Hemangiopericytoma develops from capillary vessels and is most often localized on the scalp and extremities, in the subcutaneous fat layer and skeletal muscles of the lower extremities.

Tumors and tumor-like processes in the skin vessels: causes, symptoms, diagnosis, treatment

The basis of tumor-like processes observed in the skin vessels is embryonic dysplasia, accompanied by the splitting off of angioblastic elements, which, starting from the embryonic period, proliferate and form various types of hamartomas.

Cutaneous chondroma and osteoma of the skin: causes, symptoms, diagnosis, treatment

Cutaneous chondroma is localized mainly on the fingers and toes, less often in other parts of the limbs, but, as a rule, near the joints.

Liposarcoma

Liposarcoma (syn.: myxoma lipomatodes maligna, myxoides liposarcoma) is a malignant tumor of adipose tissue, rarely developing in the subcutaneous tissue, especially in the intermuscular fascia of the thighs with subsequent invasion of the subcutaneous fat layer.

Hibernoma (brown lipoma): causes, symptoms, diagnosis, treatment

Hibernoma (syn.: brown lipoma, granular cell tumor of adipose tissue, lipoblast lipoma) develops from lipochrome-rich brown adipose tissue, most often in middle-aged and elderly women, in places where brown fat is localized in the form of rudimentary remnants (along the spine, on the neck, in the armpits, in the groin, lumbar and gluteal regions).

Fibrosarcoma

Fibrosarcoma is a tumor of connective tissue origin that can develop from the subcutaneous tissue, fascia, tendons, and intermuscular connective tissue.

Desmoid skin tumor: causes, symptoms, diagnosis, treatment

Desmoid tumor of the skin (syn.: abdominal desmoid, muscular-aponeurotic fibromatosis, desmoid fibroma) is a benign tumor that develops from the aponeurosis of muscles.

Papillary syringoadenoma: causes, symptoms, diagnosis, treatment

Papillary syringoadenoma (syn.: papillary eccrine adenoma, papillary syringocystadenoma, papillary syringocystadenomatous nevus; papillary tubular adenoma is a rare tumor, localized more often on the skin of the distal parts of the extremities in the form of a clearly demarcated hemispherical nodule, sometimes with a semi-translucent wall, 0.5-1.5 cm in diameter.

Chondroid syringoma: causes, symptoms, diagnosis, treatment

Chondroid syringoma (syn.: mucinous hidradenoma, the so-called mixed skin tumor) occurs predominantly in men and can be observed on various parts of the body, but most often on the scalp, face and neck.
