1. Case for diagnosis. A pruritic eruption of keratotic papules over the face and neck,
Abstract Generalized eruptive keratoacanthoma of Grzybowski is a rare variant of multiple keratoacanthomas counting with about 40 cases reported. It is a chronic and progressive disease for which none of the described therapeutic options has been entirely satisfactory. We report a case of an 83-year-old female who presented with a 3-month history of extremel

2. Prevalence of infection by Bartonella spp. in patients with psoriasis,
Abstract Generalized eruptive keratoacanthoma of Grzybowski is a rare variant of multiple keratoacanthomas counting with about 40 cases reported. It is a chronic and progressive disease for which none of the described therapeutic options has been entirely satisfactory. We report a case of an 83-year-old female who presented with a 3-month history of extremel

3. Multiple giant angiokeratoma of Fordyce on the shaft of the penis masquerading as keratoacanthoma
AbstractThe term 'angiokeratoma' includes a wide range of dermatological conditions of hyperkeratotic vascular disorders with a similar histologic combination of hyperkeratosis and superficial dermal vascular ectasia. Angiokeratomas can be classified into localized and systemic forms. Angiokeratoma of Fordyce (AKF) is a localized form of angiokeratoma, clini

4. Estudo comparativo da angiogenese, expressão de p53 e indice proliferativo em lesões ceratoacantoma-similes, com enfase na regressão clinica / Comparative study of angiogenesis, p53 expression and proliferation index in keratoacanthomas and squamous cell carcinomas
Keratoacanthoma (KA) is a cutaneous tumor of great interest because of its unique characteristics and controversial relationship to squamous cell carcinoma (SCC). We hypothesized that differences in microvessel density (MVD), p53 expression and proliferation index could be related to the distinct behavior between KAs and SCCs and that their assessment could

5. Keratoacanthoma of the inferior lip: review and report of case with spontaneous regression
Keratoacanthoma (KA) is a self-limited benign epithelial proliferative lesion that eventually presents with very similar clinical features to squamous cell carcinoma. Many KA appear in the vermilion border of the lips and therefore dental professionals must be familiar of the disease. This article reports the case of a 40-year-old female patient presenting w

6. HistoquÃmica e anÃlise digital de imagens em neoplasias cutÃneas
This work evaluated alterations in the expression of carbohydrates and the density of tumour cells and Langerhans cells (LC) using lectin histochemistry, immunohistochemistry and computer image analysis in neoplasic cutaneous tissues. Biopsies of basal cell carcinoma (BCC, n=35), epidermoid carcinoma (EpC, n= 18), tricoepithelioma (TE, n=12), keratoacanthoma

7. Condyloma latum mimicking keratoacanthoma in patient with secondary syphilis.
A 31 year old man with a condyloma latum simulating a keratoacanthoma at the umbilicus is reported. The umbilicus should be included in the list of known sites of predilection for condylomata lata.

9. Giant keratocanthoma on the inner surface of the prepuce.
Gian keratoacanthoma on the inner surface of the prepuce was observed in a 45-year-old man. First symptoms had appeared three months earlier. The tumour was surgically removed. The main histological features of the tumour were enormous, but relatively regular, acanthosis of rete pegs revealing no similarity to the squamous-cell carcinoma, and an exclusively

10. H-ras activation in benign and self-regressing skin tumors (keratoacanthomas) in both humans and an animal model system.
The involvement of the ras oncogenes in tumorigenesis was investigated in keratoacanthomas, which are benign and self-regressing skin tumors, both in humans and in a corresponding animal model system. Keratoacanthomas were induced on rabbit ears by repeated applications of 7,12-dimethylbenz(a)anthracene. About 60% of the tumor DNAs produced transformed foci
