The disseminated, miliarial type of lymphocytoma cutis (DMLC) is a clinicopathologic subtype of lymphocytoma, characterized by multiple, 1-2 mm translucent asymptomatic papules located in the exposed areas of the head and neck. DMLC represents a multifocal hyperplasia of B-lymphocytes with follicular differentiation and formation of follicular germinal centres. The evolution of the disease is characteristic, with some of the lesions resolving and other progressing to nodules or pseudolymphomas. The disease has a chronic course, with complete resolution in one to several years.

Association between dermatitis herpetiformis and gluten enteropathy is well established. An increased incidence of malignant disease has been reported in patients with coeliac disease and also in dermatitis herpetiformis. Linear IgA dermatitis herpetiformis has a much lower incidence of associated enteropathy compared with patients with papillary dermatitis herpetiformis, but the risk of malignancy could be the same. We report a case of linear IgA dermatitis herpetiformis in which immunoblastic sarcoma subsequently developed.
Clear cell acanthoma is a benign tumor reported by Degos et al. in 1962. Most commonly the acanthoma presents as a solitary nodule on the lower limb in late middle-aged persons. We've found only 11 papers about multiple clear cell acanthoma. We describe a 73 years old patient who had 21 lesions, the highest number found in the literature.

Malignant change in some keratinous cysts is a possible but rare condition. It seems acceptable that many publications concerning squamous cell carcinomas arising from previous cysts, actually correspond to the entity which Wilson-Jones called "proliferating epidermoid cyst" and they must be considered as pseudomalignant lesions, despite the presence of some features that may lead to a diagnosis of carcinoma. Although it is rare, which is nowadays called "proliferating Trichilemmal cyst", should be widely acknowledged since its misdiagnosis as squamous cell carcinoma leads to surgical treatment which is more drastic than necessary. Herein is presented an unusually situated case of proliferating Trichilemmal cyst and a review of the principal characteristics that have been pointed out in this tumor.
Juvenile fibromatosis has been largely studied by several authors. Most of them have pointed out the existence of some disorders which are difficult to classify and possess peculiar features. The authors report the case of a girl who presented several tumoral lesions located on the soles and toes from birth. The clinical aspect and the histological study didn't allow us to include this patient in any determinates group. She also presented some associated skeletal alterations.
