DefinitionThis section has been translated automatically.
Benign gynaecotropic tumour ( leiomyoma), located deep in the cutaneous and subcutaneous area, painful, consisting of smooth muscle fibres, spontaneously or under pressure or due to temperature differences.
ManifestationThis section has been translated automatically.
Predominantly in women in the 4th to 6th decade of life.
LocalizationThis section has been translated automatically.
Particularly proximal extremities, especially lower extremities.
Clinical featuresThis section has been translated automatically.
Solitary, mostly painful (> 50% of tumours), 1.0 cm to max. 2.0 cm Ø, firm, skin-coloured nodules in the deep dermis or subcutis.
HistologyThis section has been translated automatically.
- In the deep dermis (20% of cases) or subcutaneously (80% of cases) sharply encapsulated tumour nodes consisting of strands of densely packed smooth muscle fibres. Either a central vessel lumen or several incised vessels are visible. Depending on the vascularisation and structure of the vessels, solid, cavernous, venous or fatty variants can be distinguished. Cell polymorphisms are detectable in older tumours (degenerative).
- Immunohistology: Cells are positive for desmin (intermediate filament; see cytoskeleton below).
- The angiolipoleiomyovarian is the angiolipoleiomyoma of wall-thick vessels with interspersed mature-cell fat tissue. After its excision the tumour remains recurrence-free.
Differential diagnosisThis section has been translated automatically.
Glomus tumor, leiomyoma, neurinoma, angiofibroma, dermatofibroma. S.u. ANGLES for other pressure painful tumours of the skin
TherapyThis section has been translated automatically.
Usually not necessary, because of benign tumor and histological random findings. In case of spontaneous or pressure pain, excision may be necessary.
