- Axillary papules: an uncommon location of lichen nitidus(2021) BELDA JUNIOR, Walter; CRIADO, Paulo Ricardo; CHIACCHIO, Nilton Gioia Di
- Cutaneous New World Leishmaniasis on a Port-wine stain birthmark(2014) CRIADO, Paulo Ricardo; VALENTE, Neusa Sakai; NODA, Aliene; BELDA JUNIOR, WalterWe present an interesting case report of two sarcoid-like lesions on a port-wine stain (PWS) birthmark in a Brazilian patient which on investigation proved to be cutaneous leishmaniasis.
- Tungiasis under dermoscopy: in vivo and ex vivo examination of the cutaneous infestation due to Tunga penetrans(2013) CRIADO, Paulo Ricardo; LANDMAN, Gilles; REIS, Vitor Manoel Silva dos; BELDA JUNIOR, WalterThe female flea Tunga penetrans is responsible for a cutaneous parasitosis known as Tungiasis. We report the clinical case of a 12 year-old Caucasian boy who sought treatment in a dermatological private office due to a painful lesion in the plantar area and whose dermoscopic examination, without skin contact, allowed the visualization of parasite's movement inside the skin. The diagnosis of tungiasis is clinical, but it can be aided by in vivo and ex vivo dermoscopic examination of the lesion.
- Donovanosis(2020) BELDA JUNIOR, WalterDonovanosis is a chronic, progressive, and indolent bacterial disease that affects the skin and mucous membranes of the genital and perigenital regions, often associated with sexual transmission, and with low infectivity. The malignant transformation of donovanosis lesions occurs exceptionally, as is usually seen in long-term ulcerations. (C) 2020 Sociedade Brasileira de Dermatologia.
- A prospective, open, comparative study of 5% potassium hydroxide solution versus cryotherapy in the treatment of genital warts in men(2014) CAMARGO, Caio Lamunier de Abreu; BELDA JUNIOR, Walter; FAGUNDES, Luiz Jorge; ROMITI, RicardoBACKGROUND: Genital warts are caused by human papillomavirus infection and represent one of the most common sexually transmitted diseases. Many infections are transient but the virus may recur, persist, or become latent. To date, there is no effective antiviral treatment to eliminate HPV infection and most therapies are aimed at the destruction of visible lesions. Potassium hydroxide is a strong alkali that has been shown to be safe and effective for the treatment of genital warts and molluscum contagiosum. Cryotherapy is considered one of the most established treatments for genital warts. No comparative trials have been reported to date on the use of potassium hydroxide for genital warts. OBJECTIVE: A prospective, open-label, randomized clinical trial was conducted to compare topical potassium hydroxide versus cryotherapy in the treatment of genital warts affecting immunocompetent, sexually active men. METHODS: Over a period of 10 months, 48 patients were enrolled. They were randomly divided into two groups and selected on an alternative basis for either potassium hydroxide therapy or cryotherapy. While response to therapy did not differ substantially between both treatment modalities, side effects such as local pain and post-treatment hypopigmentation were considerably more prevalent in the groups treated using cryotherapy. Result: In our study, potassium hydroxide therapy proved to be at least as effective as cryotherapy and offered the benefit of a better safety profile. CONCLUSION: Topical 5% potassium hydroxide presents an effective, safe, and low-cost treatment modality for genital warts in men and should be included in the spectrum of therapies for genital warts.
- Multinucleate cell angiohistiocytoma: an uncommon cutaneous tumor(2020) COSTA, Anderson Alves; WEDY, Glaucia Ferreira; BELDA JUNIOR, Walter; CRIADO, Paulo RicardoMultinucleate cell angiohistiocytoma is a rare, benign vascular proliferation of unknown etiology. It occurs mainly in middle-aged women and usually affects the acral regions; the lesions appear as discrete, grouped, and asymptomatic violaceous papules. Histopathology shows proliferation and dilated small vessels in the papillary dermis, fibrous stroma with thickened collagen bundles, and multinucleated giant cells. To date, there are approximately 140 cases described in the indexed literature. This report presents the case of a 62-year-old woman with a typical clinical condition, who chose not undergo treatment, considering the benign character of her illness. The clinical and immunohistological aspects of this unusual dermatological entity are emphasized. (C) 2020 Sociedade Brasileira de Dermatologia.
- Dermoscopy and Onychomycosis: guided nail abrasion for mycological samples(2015) BET, Diego Leonardo; REIS, Ana Lucia dos; CHIACCHIO, Nilton Di; BELDA JUNIOR, WalterMycological examination is still the cornerstone for the diagnosis of onychomycosis for many dermatologists, but sampling technique interferes on its sensitivity and specificity. Nail abrasion may be used to reach the most proximal part of the lesion and can be easily accomplished with an electric abrasor. We suggest nail plate dermoscopy to identify the best location for localized abrasion to obtain adequate samples for mycological examination.
- Primary cutaneous histoplasmosis developed in the penis of an immunocompetent patient(2015) PAIXAO, Mauricio; MIOT, Helio Amante; AVANCINI, Joao; BELDA JUNIOR, WalterA 70-year-old male presenting a 3-month history of genital painless erythematous nodules in the balanopreputial sulcus was referred to our service. Histopathological exam presented a chronic dermatitis with epithelioid granulomas and Grocott staining revealed numerous fungal structures with a suggestive morphology of Histoplasma sp. Cultures evidenced Histoplasma capsulatum var. capsulatum. Treatment with oral itraconazole led to complete remission of lesions.
article Zoon's plasma cell balanitis: a report of two cases treated with pimecrolimus(2011) DELGADO, Livia; BRANDT, Hebert Roberto Clivati; ORTOLAN, Damaris G.; PATRIOTA, Regia Celli Ribeiro; CRIADO, Paulo Ricardo; BELDA JUNIOR, WalterInitially called (in French) ""Balanoposthite chronique circonscrite benigne a plasmocytes"", Zoon's plasma cell balanitis is a chronic inflammatory dermatosis affecting the glans and foreskin of uncircumcised men. The different treatment options for this condition often present partial results. Reports have shown therapeutic success using topical tacrolimus. We report the use of pimecrolimus, a homologue of tacrolimus, with good response. Two male patients diagnosed with Zoon's plasma cell balanitis, confirmed by biopsy, were subjected to daily treatment with topical pimecrolimus1%. Significant improvement was noted in patient 1 after 6 weeks and after 8 weeks in patient 2. Conclusion: Pimecrolimus cream may be an option for the treatment of this disease.
