2. Rosettes in T-cell pseudolymphoma: a new dermoscopic finding,
Abstract Rosettes are small white structures visible with polarized light dermoscopy, whose exact morphological correlation is not yet defined. These small shiny structures are found in several conditions such as scarring, dermatofibroma, molluscum contagiosum, squamous cell carcinoma, basal cell carcinoma, melanoma, melanocytic nevus, discoid lupus erythema

3. Immunohistochemical analysis of S100-positive epidermal Langerhans cells in dermatofibroma,
Abstract Dermatofibroma is a dermal fibrohistiocytic neoplasm. The Langerhans cells are the immunocompetent cells of the epidermis, and they represent the first defense barrier of the immune system towards the environment. The objective was to immunohistologically compare the densities of S100-positive Langerhans cells in the healthy peritumoral epidermis ag

4. Scanning electron microscopy of dermatofibroma
Abstract: Dermatofibroma is a proliferation of spindle cells located in the dermis. We used scanning electron microscopy to examine two histologically confirmed lesions and observed preserved collagen bundles in the perilesional area. In the lesional area, the collagen was denser, without formation of bundles. Higher magnification showed collagen with mesh-l

5. Wade’s histoid leprosy in a 14-year-old teenage boy
Abstract Wade’s histoid leprosy (HL) is a rare variant of multibacillary leprosy, with characteristic clinical, immunologic, histopathologic, and bacteriologic features. It is associated with resistance to sulfa drugs or polychemotherapy and is rarely observed in patients who have not undergone prior treatment. Clinically, HL resembles keloid or dermatofib

6. Hemosiderotic dermatofibroma
Abstract: We report a rare clinical case of hemosiderotic dermatofibroma in a 36-year-old female patient. The main dermatoscopic finding was represented by homogeneous blue-gray pigmentation. The aim of this report is to demonstrate the rarity of the lesion and the dermatoscopic importance it assumes by sharing a blue-gray homogeneous pattern with other beni

7. Dermatofibroma simulating seborrheic keratosis dermoscopically
Abstract: Dermatofibroma is a frequent benign tumor of easy clinical diagnosis in most cases, but that can mimic other dermatoses. Dermoscopy may help to define the diagnosis and its classical pattern is a central white area, similar to a scar, surrounded by a discrete pigment network. However, dermoscopic findings are not always typical. We describe here a

8. Colagenoma estoriforme: relato de caso
O colagenoma estoriforme é um tumor raro originado a partir da proliferação de fibroblastos com produção aumentada de colágeno tipo I. É encontrado mais frequentemente na face, pescoço e extremidades, podendo aparecer no tronco, couro cabeludo e, raramente, na mucosa oral e leito subungueal. Afeta ambos os gêneros, com discreta predominância em mul

9. Case for diagnosis
We report the case of an 11-year-old male patient with a histopathological and immunohistochemical diagnosis of dermatofibroma with an atypical clinical presentation on the right forearm. Although dermatofibroma is considered a benign skin tumor, some of its differential diagnoses, such as dermatofibrosarcoma protuberans and malignant fibrous histiocytoma, a

10. Variants of dermatofibroma - a histopathological study
Several variants of dermatofibroma have been described. They are essentially distinguished by their clinical and histopathological features. To review the mainfeaturesof these variants, a retrospective study of skin biopsies and tissue excisions of dermatofibromasperformed in the dermatology and venereology service at the Hospital Garcia de Orta between May

11. Dermatofibroma múltiplo agrupado congênito e dermatofibromas múltiplos eruptivos - apresentações singulares de uma entidade comum
O dermatofibroma é uma das entidades mais frequentemente observadas na prática clínica dermatológica. No entanto, além do dermatofibroma comum, vários subtipos clínicos de ocorrência incomum têm sido descritos na literatura. Os autores descrevem duas variantes clínicas raras de dermatofibromas: dermatofibroma múltiplo agrupado congênito (o caso a

12. Dermatofibroma atrofico
O dermatofibroma é um tumor fibrohistiocitário benigno, comum e facilmente diagnosticado quando apresenta os achados clinicopatológicos clássicos. O dermatofibroma atrófico é uma variante específica do dermatofibroma, de origem ainda incerta. Esta é caracterizada clinicamente por lesão plana ou atrófica, depressível à compressão. Ao exame histop
