Malignant eccrine spiradenomaL74.8
DefinitionThis section has been translated automatically.
Very rare, undifferentiated, malignant adnexal tumor developing at the base of a spiradenoma.
LocalizationThis section has been translated automatically.
The head, neck, upper trunk area or bending sides of the arms are affected. Infestation of the vulva is described.
Clinical featuresThis section has been translated automatically.
Mostly solitary, suddenly growing node, which has grown on the ground of a pre-existent spiradenoma. The clinical picture is not very characteristic apart from the possible painfulness. The diagnosis is generally a histological accidental finding.
HistologyThis section has been translated automatically.
In most cases the very distinct histological morphology of the spiradenoma is still detectable with a deeply dermal nodular tumor complex, partly consisting of one or more nodes. Parenchyma consisting of basaloid, poorly differentiated polymorphic cell complexes. Partially also spindle cell differentiation. Numerous mitoses, mass necroses. Often clear lymphocytic infiltrate.
Complication(s)This section has been translated automatically.
Metastasis in 20% of cases.
TherapyThis section has been translated automatically.
Excision according to the criteria of the spinocellular carcinoma, necessarily with marginal incision controls and lymph node mapping ( sentinel lymph node dissection).
Note(s)This section has been translated automatically.
Spiradenocarcinoma is "frequently" associated with cylindromes.
