Woods Malignant Nasal Granuloma

In UV-ACD, benign neoplasms almost always have a dermato- and polymorpho-nodular form, which, against the background of their growth, creates the impression of a more malignant lesion. In some cases, there are exceptions among benign neoplasms, which, due to their location at the boundaries of the skin and the presence of a dense horny plaque, look like malignant. R. Woods described skin lesions in the form of a terminal finger or nasal tubercle, covered with brown crusts or mushroom-shaped ulcers (cancer, syphilis, sarcoma, mastocytosis, cutaneous horn). At the same time, a symptom complex of tissue damage may occur that resembles a localized area of ​​connective tissue loss, the so-called conglobate dermatitis, usually incorrectly called eczema. Regional metastases and lymphangitis are absent in these diseases. Hemosiderosis is the deposition of hemosiderin (the blood pigment hemoglobin), causing skin pigmentation, with a characteristic “shirt-like” pattern and enlarged lymph nodes, which complicates the course of chronic inflammation of internal organs (chest cavity, intestines, etc.).
