- Guess what! Porokeratosis of Mibelli.Publication . Machado, S.; Silva, E.; Pereira, O.; Sanches, M.; Massa, A.Eur J Dermatol. 2000 Aug;10(6):485-6. Guess what! Porokeratosis of Mibelli. Machado S, Silva E, Pereira O, Sanches M, Massa A. Source Department of Dermatology, Hospital Geral de Santo António, Rua D. Mannell 11, Edificio ex-Cicap, 4099-001, Porto, Portugal. susama@esoterica.pt Abstract A 72-year-old man had noticed, in his early forties, the appearance of well-defined papulous hyperkeratotic lesions, with increasing growth, located on both sides of his feet. After twenty-five years he consulted a dermatologist for the first time. Physical examination showed annular papules and rose-coloured plaques with atrophic centres, some of them hypopigmented, with higher and irregular borders, separated from the surrounding skin by longitudinal and well-defined furrows. The lesions presented variable sizes and shapes, some of them punctate, involving exclusively and in a bilateral form, both sides, back and sole of the feet (Figs. 1 and 2). The patient did not report any subjective symptoms. He was immunocompetent and did not remember that any relative had the same disease, nor had he been subjected to radiation treatment.

- Cutaneous necrobiotic xanthogranuloma (NXG)--successfully treated with low dose chlorambucil.Publication . Machado, S.; Alves, R.; Lima, M.; Leal, I.; Massa, A.Eur J Dermatol. 2001 Sep-Oct;11(5):458-62. Cutaneous necrobiotic xanthogranuloma (NXG)--successfully treated with low dose chlorambucil. Machado S, Alves R, Lima M, Leal I, Massa A. SourceService of Dermatology, Hospital Geral Santo António, Rua D. Manuel II, Edifício ex: Cicap, 4099-001 Porto, Portugal. basleite@esoterica.pt Abstract We report a case of necrobiotic xanthogranuloma in a 51 year-old white male patient presenting with a 6-year history of multiple indurated violaceous nodules and plaques involving the eyelids, trunk and extremities. He had an associated paraproteinemia (Ig G lambda), elevated sedimentation rate, cryoglobulinemia and hypocomplementemia. No extracutaneous involvement was detected. He was successfully treated with chlorambucil (2 mg/d for 7 months), leading to disappearance of all skin lesions.
- ErisipelaPublication . Caetano, M.; Amorim, I.A erisipela é uma infecção dermo-hipodérmica aguda, não necrosante, geralmente causada pelo estreptococo β–hemolítico do grupo A. Em mais de 80% dos casos situa-se nos membros inferiores e são factores predisponentes a existência de solução de continuidade na pele, o linfedema crónico e a obesidade. O seu diagnóstico é essencialmente clínico e baseia-se na presença de placa inflamatória associada a febre,linfangite, adenopatia e leucocitose. Os exames bacteriológicos têm baixa sensibilidade ou positividade tardia. Nos casos atípicos é importante o diagnóstico diferencial com a fasceíte necrosante e a trombose venosa profunda. A penicilina continua a ser o antibiótico de referência, embora actualmente diversos fármacos, com propriedades farmacodinâmicas mais favoráveis, possam ser utilizados. A recidiva constitui a complicação mais frequente, sendo fundamental o correcto tratamento dos factores de risco.
- Eruptive syringomasPublication . Teixeira, M.; Ferreira, M.; Machado, S.; Alves, R.; Selores, M.Eruptive syringoma is a rare clinical presentation of a benign tumor of the eccrine ducts. It consists in successive crops of small skin-colored papules on the anterior body surfaces. It generally occurs in the peri-pubertal period. Treatment of this benign condition is cosmetic only. A case of a 19-year-old female with a 5-year history of eruptive syringoma is presented.
- Leukemia cutis resembling a flare-up of psoriasisPublication . Ferreira, M.; Caetano, M.; Amorim, I.; Selores, M.Abstract Leukemia cutis represents a skin infiltration by leukemic cells. Clinically it can mimic a wide variety of dermatoses. We describe the case of a 64-year-old man with psoriasis who presented with a 4-day history of erythematous, slightly scaly, asymptomatic plaques distributed on the trunk and upper-extremities, and associated asthenia, myalgias, and anorexia. A skin biopsy revealed a leukemic infiltrate. Studies of peripheral blood and bone marrow provided a diagnosis of acute monocytic leukemia. This case report shows the importance of the clinical suspicion for the diagnosis of leukemia.

- Allergic contact dermatitis to Aloe veraPublication . Ferreira, M.; Teixeira, M.; Silva, E.; Selores, M.Abstract We present the case of a 72-year-old woman observed for dermatitis on the legs followed by apperance of erythema on the eyelids. She had a past history of peripheral venous insufficiency and had been using self home-made Aloe vera juice over the legs for relief from pain. Patch tests showed positive reactions to the leaf of Aloe, the macerated Aloe jelly, and nickel sulfate. Although most manufacturers process Aloe products avoiding its irritant extracts, and probably as a consequence reports of allergic reactions are rare, one must remember that the growing popularity on the use of Aloe products may stimulate its use ‘as is’ by the patients. Furthermore, it is important to specifically ask patients about the use of these products, because they consider it as innocuous and thus would not spontaneously provide such information
- Calcinosis cutis: A rare feature of adult dermatomyositisPublication . Lobo, I.; Machado, S.; Teixeira, M.; Selores, M.Abstract Dermatomyositis is an idiopathic inflammatory myopathy with characteristic cutaneous manifestations. We describe a case of a 55- year-old woman with dermatomyositis who presented with dystrophic calcinosis resistant to medical treatment.
- Persistent varicella as the initial manifestation of systemic lymphomaPublication . Ferreira, M.; Sanches, M.; Teixeira, M.; Guerra, M.; Selores, M.Varicella is a common benign childhood disease that often presents in adolescents and adults in a more severe form. We report a previously healthy 50-year-old man who developed multiple necrotic cutaneous ulcers associated with fever, asthenia and anorexia. Physical examination revealed few tense hemorrhagic vesicles on the trunk and necrotic cutaneous ulcers scattered over the entire cutaneous surface. After the diagnosis of varicella with varicella pneumonia was established, treatment with acyclovir was instituted. His poor response to treatment was indicative of immune compromise; an underlying peripheral T-cell lymphoma was discovered.
