Diseases of the skin and subcutaneous tissue (dermatology)

Skin histiocytosis X: causes, symptoms, diagnosis, treatment

Histiocytosis X (syn: histiocytic medullary reticulosis, malignant reticulogistiocytosis). Histiocytosis from the cells of Langerhans make up a group that includes the Letterer-Sieve disease, the Hend-Schuller-Crischen disease, the eosinophilic granuloma

Pagetoid reticulosis: causes, symptoms, diagnosis, treatment

Pagetoidic reticulosis (blue sickness of Vorenje-Koloppa). Described by FR Woringer and P. Kolopp in 1939. The term "pagetoid reticulosis" was introduced by O. Biaun-Falco et al. In 1973, on the basis of the observed invasion of the lower layers of the epidermis by atypical cells with a light cytoplasm, reminiscent of the appearance of Paget cells.

Cesary Syndrome

Cesari syndrome is an erythrodermic form of T-cell malignant skin lymphoma with an increased number of large atypical lymphocytes with cerebriform nuclei in the peripheral blood.

Mushroom mycosis

Mushroom-like mycosis refers to low-grade T-cell lymphomas. Characteristic for this disease is the primary lesion of the skin, a long time without lesions of lymph nodes and internal organs. The latter are mainly affected in the final stage of the disease.

Lymphocytic papulosis: causes, symptoms, diagnosis, treatment

The first description of the disease of lymphocytic papulosis belongs to A. Dupont (1965). In 1968, WL Macauly introduced the term "lymphomatoid papulosis" for long-term, benign, self-healing papular rashes, histologically having a malignant appearance.

Pseudolymphomas of the skin: causes, symptoms, diagnosis, treatment

Skin pseudolymphomas are a group of benign lymphoproliferative processes of a reactive nature of a local or disseminated type that can be resolved after removal of the damaging agent or non-aggressive therapy.

Lymphoproliferative skin diseases: causes, symptoms, diagnosis, treatment

Diagnostic evaluation of benign and malignant lymphoproliferative skin diseases presents a very difficult task for the pathomorphologist. In recent decades, significant progress has been made in this direction, related to the success of immunology.

Neurinoma (schwannoma): causes, symptoms, diagnosis, treatment

Neurilemoma (syn: neurinoma, schwannoma) - a benign tumor of neirolemmotsitov skull or spinal peripheral nerves. It is localized in the subcutaneous tissue of the head, trunk and extremities along the nerve trunks.

Skin neuroma: causes, symptoms, diagnosis, treatment

Skin neuroma is a tumor-like proliferation of nerve tissue. There are traumatic, idiopathic (solitary or multiple) and multiple neuromas of the mucous membranes. The latter represents the result of multiple endocrine neoplasia of type 26.

Hemangioendothelioma (angiosarcoma): causes, symptoms, diagnosis, treatment

Hemangioendothelioma (synovial angiosarcoma) is a malignant tumor that originates from the endothelial elements of the blood and lymphatic vessels. WF Lever and O. Sehaurnburg-Lever (1983) distinguish two types of this tumor: angiosarcoma developing on the head and face in the elderly, and angiosarcoma secondary, occurring in chronic lymphatic edema (Stewart-Trivs syndrome).
