However over the years, evidence of links between the use of dental materials and lately, significant involvement of aesthetic filler materials as foreign bodies in the oral and perioral region have been reported. Foreign body granulomas (FBGs) may develop from this exogenous material, histopathologically characterized by the presence of chronic inflammation and a high amount of macrophages. This study presents nine FBG cases affecting the oral and perioral regions, and carries out a literature review on the main clinical, histopathological and material characteristics used in dental and dermatological procedures related to the appearance of this type of granuloma.

The lesion was presented in six cases (66.6%) as a fibrotic nodule, in three cases the duration ranged from 2 to 60 months and six cases were asymp- tomatic.

    Volume 20 Number 4 April 2014 Review An atlas of the morphological manifestations of hidradenitis suppurativa Noah Scheinfeld Dermatology Online Journal 20 (4): 4 Weil Cornell Medical College Correspondence: Noah Scheinfeld MD JD Assistant Clinical Professor of Dermatology Weil Cornell Medical College 150 West 55th Street NYC NY [email protected] Abstract This article is dermatological atlas of the morphologic presentations of Hidradenitis Suppurativa (HS). It includes: superficial abscesses (boils, furnucles, carbuncles), abscesses that are subcutaneous and suprafascial, pyogenic granulomas, cysts, painful erythematous papules and plaques, folliculitis, open ulcerations, chronic sinuses, fistulas, sinus tracts, scrotal and genital lyphedema, dermal contractures, keloids (some that are still pitted with follicular ostia), scarring, skin tags, fibrosis, anal fissures, fistulas (i.e. circinate, linear, arcuate), scarring folliculitis of the buttocks (from mild to cigarette-like scarring), condyloma like lesions in intertrigous areas, fishmouth scars, acne inversa, honey-comb scarring, cribiform scarring, tombstone comedones, and morphia-like plaques. HS can co-exist with other follicular diseases such as pilonidal cysts, dissecting cellulitis, acne conglobata, pyoderma gangrenosum, and acanthosis nigricans. In sum, the variety of presentations of HS as shown by these images supports the supposition that HS is a reaction pattern. HS is a follicular based diseased and its manifestations involve a multitude of follicular pathologies [1,2]. It is also known as acne inversa (AI) because of one manifestation that involves the formation of open comedones on areas besides the face. It is as yet unclear why HS is so protean in its manifestations. HS severity is assessed using the Hurley Staging System (Table 1).

Present for 4 weeks. Nodular fasciitis is a self-limited pseudosarcomatous proliferation that may cause clinical alarm due to its rapid growth. It is most common in young adults but occurs across a wide age range. This lesion is typically 3-5 cm and composed of bland fibroblasts and myofibroblasts without significant cytologic atypia arranged in a loose storiform pattern with areas of extravasated red blood cells. Mitoses may be numerous, but atypical mitotic figures are absent. Nodular fasciitis is a benign process, and recurrence is very rare (1%). Recent work has shown that the MYH9-USP6 gene fusion is present in approximately 90% of cases, and molecular techniques to show USP6 gene rearrangement may be a helpful ancillary tool in difficult cases or on small biopsy samples.

Caso Clínico Dermatose Degenerativa Induzida por D-penicilamina em Paciente com Doença de Wilson Rui Pedro Santos1, Joana Gomes2, Celeste Brito2 1Interno de Dermatovenereologia/Resident, Dermatovenereology, Hospital de Braga, Braga, Portugal 2Especialista de Dermatovenereologia/Specialist of Dermatovenereology, Hospital de Braga, Braga, Portugal RESUMO – As dermatoses degenerativas induzidas por D-penicilamina incluem, entre outras, a elastose perfurante serpiginosa e o pseudo-pseudoxantoma elástico. A elastose perfurante serpiginosa é uma doença perfurante rara caracterizada pela elimi- nação transepidérmica de fibras elásticas anormais. Esta condição pode ser idiopática, reativa ou induzida por D-penicilamina, habitualmente utilizada para o tratamento da doença de Wilson, cistinúria, artrite reumatóide ou esclerose sistémica. Manifesta- ções cutâneas semelhantes a pseudoxantoma elástico mas sem história familiar e mutações do gene ABCC6 foram identificadas como sendo uma dermatose induzida por D-penicilamina e designada de pseudo-pseudoxantoma elástico. Descreve-se o caso de uma mulher de 17 anos tratada por vários anos com D-penicilamina para doença de Wilson, com pápulas assintomáticas, algumas cor de pele e hiperqueratósicas e outras macias e amareladas, na região cervical e face. A histopatolo- gia mostrou a eliminação transepidérmica de fibras elásticas espessadas, em forma de dentes de serra. Estes achados sugeriram uma dermopatia induzida por D-penicilamina e os autores consideraram o diagnóstico de elastose perfurante serpiginosa e pseudo-pseudoxantoma elástico no mesmo paciente. O fármaco foi alterado para acetato de zinco sem lesões novas, mas com manutenção das lesões existentes no seguimento a 1 ano.

Description Individuals may acquire a multitude of benign skin lesions over the course of a lifetime. Most benign skin lesions are diagnosed on the basis of clinical appearance and history. If the diagnosis of a lesion is uncertain, or if a lesion has exhibited unexpected changes in appearance or symptoms, a diagnostic procedure (eg, biopsy, excision) is indicated to confirm the diagnosis. The treatment of benign skin lesions consists of destruction or removal by any of a wide variety of techniques. The removal of a skin lesion can range from a simple biopsy, scraping or shaving of the lesion, to a radical excision that may heal on its own, be closed with sutures (stitches) or require reconstructive techniques involving skin grafts or flaps. Laser, cautery or liquid nitrogen may also be used to remove benign skin lesions. When it is uncertain as to whether or not a lesion is cancerous, excision and laboratory (microscopic) examination is usually necessary. II.

Summary: Many connective tissue disorders involve the lungs. The same clinical syndrome may be associated with several distinctive types of pathology in different patients. Fibrosing alveolitis is a common feature of a number of different syndromes. An hypothesis is set out in schematic form which may help to account for some of these differences and emphasizes the potential importance of the pulmonary vasculature in pathogenesis.

While some pyogenic granulomas may resolve spontaneously, most have a tendency to bleed easily and require treatment. Current therapeutic modalities include topical imiquimod, cryotherapy, electrodessication, curettage, excision, laser therapy, sclerotherapy, and microembolization. We report a recalcitrant case of chronic pyogenic granuloma occurring on the scalp of a healthy young male which was unresponsive to conventional surgical and non-surgical modalities. Ultimately, aggressive laser therapy, intralesional triamcinolone acetonide injections, and topical timolol application led to complete resolution and healing. Introduction Pyogenic granuloma (PG) is a rapidly growing benign vascular tumor on the skin or subcutaneous tissue (Table 1). Clinically, PGs present as red or purple smooth glistening papules that grow rapidly within a few days or weeks and occur most commonly on the lips and fingers.1 Also known as lobular capillary hemangiomas, PGs often bleed easily and commonly result after minor trauma, although they can develop spontaneously.
