BACKGROUND: Leprosy and HIV are diseases that have a major impact on public health in Brazil. Patients coinfected with both diseases, appear to be at higher risk to develop leprosy reactions. OBJECTIVE: The aim of this study is to describe the histopathological aspects of cutaneous lesions during reactional states in a group of patients with HIV-leprosy coinfection, compared to patients with leprosy, without coinfection. METHODS: Two groups were established: group 1 comprised of 40 patients coinfected with HIV-leprosy; group 2, comprised of 107 patients with leprosy only. Patients presenting reactional states of leprosy had their lesions biopsied and comparatively evaluated. RESULTS: Reversal reaction was the most frequent feature in both groups, with dermis edema as the most common histopathological finding. Giant cells were seen in all group 1 histopathological examinations. Dermis edema was the most common finding in patients with erythema nodosum leprosum. CONCLUSION: Few histopathological differences were found in both groups, with reversal reaction as the most significant one, although this fact should be analyzed considering the predominant BT clinical form in the coinfected group and BB form in the group without HIV. Larger prospective studies in patients with HIV-leprosy coinfection are needed to confirm and broaden these results.

Dermatofibroma in a black tattoo: report of a case
(Universidade Federal do Pará, 2012-08-01) BITTENCOURT, Maraya de Jesus Semblano; MIRANDA, Mario Fernando Ribeiro de; PARIJÓS, Amanda Magno de; FONSECA, Diana Mendes da; JAMBO, Diego Augusto Aiezza; MESQUITA, Letícia Brito
Tattooing has been associated with a variety of complications including inflammatory and granulomatous reactions, transmission of infections, and neoplasms. We report a case of a 24-year-old male who presented with a 2-month history of an erythematous nodule involving a newly made tattoo on the right leg. An excisional biopsy was performed and the histopathological evaluation was consistent with dermatofibroma. Only three cases of dermatofibroma associated with tatooing were reported in litetature. We report an additional case and review the literature regarding cutaneous reactions to tattoos.

Jorge Lobo‟s disease (JLD) or lacaziosis is a chronic, granulomatous skin and subcutaneous tissue infection caused by the fungus Lacazia loboi. Clinical lesions are generally polymorphous, often presenting with a keloid-like aspect, and most often involving ears or limbs. Histopathology remains the “gold standard” exam to reach diagnosis. Few clinical-pathological correlation studies on this disease are available to date. Our goal was to systematically review cases of JLD diagnosed at the dermatopathology laboratory of the Dermatology Service of the Federal University of Pará, Brazil, from 1967 to 2009. After a thorough chart review, we could retrieve demographic and clinical data, as well as histopathological features from each case studied. 59 biopsies from 45 patients were evaluated. The sample consisted of 37 men and eight women, with a mean age of 50 years. Most patients were agricultural workers (55%), of which 93% were males. Fifty-nine percent of the lesions showed a keloid-like appearance. Verrucous (8%), plaque (3%), gummatous (1%), and hyperchromatic macular (1%) lesions were less frequently observed. Most skin lesions occurred on the lower limbs (56%). Histopathologically, the stratum corneum showed hyperkeratosis in 71% of the biopsies, associated with parakeratosis in 37% and with orthokeratosis in 50%. Transepidermal elimination of parasites (TEP) was present in 36% of the cases in association with hyperkeratosis in 95% (p=0.0121) and with parakeratosis in 90% (p<0.0001). The epidermis showed a hyperplastic appearance in 58% of the specimens, was atrophic in 29%, normal in 12%, and ulcerated in 8% of them. There was a hyperplastic epidermis (86%, p=0.0054) in sites where TEP took place. We could also observe the presence of parasites in the epidermis in 30% of the biopsies, in which an association with TEP occurred in 89% (p<0.0001). There was no statistically significant relationship between the occurrence of TEP and the clinical aspect of the lesion (p=0.4231). Lymphocytes, macrophages and giant cells of the foreign-body type were predominant in the infiltrate, being observed in 100% of the cases. Plasma cells were seen in 35%, neutrophils in 15%, and eosinophils in 11% of the cases. There was a statistically significant relationship between the occurrence of TEP and the presence of neutrophil infiltration (p=0.0016). An exudative reaction pattern was present in 10% of the biopsies, and 11% exhibited focal areas of necrosis. Langhans giant cells were observed in 59% of the biopsies, and asteroid bodies in 5%. Pseudo-Gaucher cells were present in 69% of the cases, and fibrosis in 96%. The infiltrate showed extension to the reticular dermis in all cases, and to the deep dermis in 88%. A subcutaneous spread of the infiltrate occurred in 10% of the cases, with identification of parasites within the fat tissue in one of them. As for age distribution, sex and profession of the patients, the data overlapped those of the literature. The results allowed us to evaluate epidemiological, clinical and histopathological profiles of the disease, which in certain respects differed from the classically described ones of the literature, especially concerning characteristics of the epidermis, inflammatory cell infiltrate, and location of lesions.

Hemangiomas extensos da infância tratados com propranolol: relato de dois casos
(2011-06) CAVALEIRO, Luíza Helena dos Santos; VIANA, Fernanda de Oliveira; UNGER, Deborah Aben-Athar; BITTENCOURT, Maraya de Jesus Semblano
Hemangiomas are the most common benign tumors of childhood. They show rapid growth, followed by a regression phase that culminates in the partial or total disappearance of the lesion. Therapeutic options should be evaluated for extensive cases. Systemic glucocorticoids are the therapy of choice; however, there are reports that propranolol offers better and faster results. We report two cases of large volume infantile hemangioma associated with functional limitation and aesthetic disfigurement, treated successfully with propranolol, a drug that comes as a therapeutic option providing satisfactory and maintained results, with few side effects.

Leucodermia sifilítica: expressão rara do secundarismo diagnosticada por exame histopatológico
(Universidade Federal do Pará, 2010-08) MIRANDA, Mario Fernando Ribeiro de; BITTENCOURT, Maraya de Jesus Semblano; LOPES, Igor da Costa; CUMINO, Shirley do Socorro Magalhães
Biopsies are occasionally necessary to confirm the diagnosis of secondary-stage syphilis, currently achieved by clinico-serological correlation. However, histopathologic examination may offer clues that can lead to the diagnosis of the disease in previously unsuspected or unusual cases. We report the case of a 35-year-old male patient with vitiligo-like lesions for two years, whose diagnosis of syphilis was suggested only after histopathologic examination. Some microscopic aspects observed are discussed and compared to data from the literature.

Pencil-core granuloma
(Universidade Federal do Pará, 2017-08) BITTENCOURT, Maraya de Jesus Semblano; SANTOS, Josie Eiras Bisi dos; BARROS JUNIOR, Jorge Nazareno da Silva; XERFAN, Ellen Maria Sampaio
Pencil core granulomas are still infrequently reported in the literature. A 67-year-old woman presented with a 4mm hard blue subcutaneous nodule on the forehead. She remembered being injured with a pencil tip about 60 years before. The subcutaneous nodule was excised, which microscopically revealed a foreign body reaction with histiocytes containing fragmented coarse black particles. We diagnosed pencil-core granuloma based on the patient’s history of pencil tip injury and histological examination findings.

Primary cutaneous follicle center lymphoma
(Universidade Federal do Pará, 2016-03-07) COSTA, Eline Pinheiro Weba; LUCENA, Bethänia Dias de; AMIN, Gabriela Athayde; BITTENCOURT, Maraya de Jesus Semblano; DIAS JUNIOR, Leonidas Braga; PIRES, Carla Andréa Avelar
Cutaneous lymphomas are classified according to their cellular origin into T-cell lymphoma and B-cell lymphoma. The annual incidence rate is 0.3 per 100,000 population. We report a case of a 56-year-old male patient who presented with a two-month history of nodules of varying sizes, some ulcerated, on the face, abdomen, and upper limbs. Histopathological examination and immunohistochemical study confirmed the diagnosis of primary cutaneous centrofollicular lymphoma. Studies have shown an increased incidence of non-Hodgkin lymphomas in the last decade. We report an infrequent case that should be kept as a differential diagnosis of patients with nodules and cutaneous papules.
