There are many clinical types of amyloidosis, as many as chemical types of amyloid substance would be its substratum. This clinic-chemical plurality permits us to talk about the amyloidosis. This article is specially guided to those amyloidosis that present cutaneous damages during its clinical course. They are the immunocytic amyloidosis and the keratinocytic amyloidosis.
The CAQ is a tumor of the major and minor salivary glands, of superior airway glands, uterine cervix glands, and the Bartholin glands of the vulva. However, recently, primary cases of CAQ of the skin, originating in eccrine sweat glands were described. We report 2 CAQ cases, one, case 1, of minor salivary glands of the palate, that by extension, reached the skin of the face, finishing with kidney metastasis; and its histological type corresponded to the cribiform variety in both the primary tumor and the kidney metastasis. Case 2 presented in the parotid gland and its histological type is the solid variety of the CAQ.
Pilomatrixoma presents clinical variants, ulcerated and tumorous, angioid and one very special type characterized because the skin covering the tumor is very thin (anetodermic), pink and folded, simulating an involuting blister. The authors that observed six cases of this variant, considered that for this reason they can name it the "pseudoblistering form of pilomatrixoma". The histopathology that appears in this pseudoblistering variant is characteristic because the collagen existing between the tumor and the epidermis is atrophied and its fibers are separated by the intense edema.
