- Coma BlistersPublication . Rocha, J; Pereira, T; Ventura, F; Pardal, F; Brito, CComa blisters are lesions that occur in the setting of a variety of neurological diseases. Although most commonly associated with barbiturate overdose, they can be seen in the setting of coma due to other etiologies. Blisters develop 48-72 h after the onset of unconsciousness. We report the case of a 29-year-old man who presented to the emergency department with confusion and progressive loss of consciousness. He had high serum glucose, abnormal hepatic and kidney function tests and a normal toxicological screening. 24 h after admission he was comatose and was started on antibiotics for presumed bacterial meningoencephalitis. Two days after the onset of coma, multiple tense hemorrhagic blisters appeared on the patient's extremities. Skin biopsy revealed an intraepidermal blister with variable degrees of epidermal necrosis. Five days later the patient was fully recovered with no neurological sequelae. No topical treatment was necessary, with complete resolution of the skin lesions two weeks later.

- Indeterminate cell histiocytosis in association with acute myeloid leukemiaPublication . Ventura, F; Pereira, T; Duarte, ML; Marques, H; Pardal, F; Brito, CIndeterminate cell histiocytosis (ICH) is a rare proliferative disorder, in which the predominant cells share morphologic and immunophenotypic features from both Langerhans and non-Langerhans cell histiocytosis. We describe a 62-year-old man presenting a 2-month history of firm nodular lesions on the upper lip. Histopathology, immunohistochemical, and ultrastructural analysis showed typical findings of ICH. The patient was treated with thalidomide and almost complete regression of the lesions was reached within 7 months. Nevertheless, one month after remission, he developed an acute myeloid leukemia of the subtype monocytic leukemia (M5). The patient's condition rapidly worsened and he died due to a respiratory failure four weeks later. We present this case because apart of being rare it joins the effectiveness of thalidomide and the association with an acute monocytic leukemia. A review of the literature is made.

- Topical Imiquimod Treatment of Lentigo MalignaPublication . Ventura, F; Rocha, J; Fernandes, JC; Pardal, F; Brito, CLentigo maligna (LM) is the in situ phase of lentigo maligna melanoma, which may progress to invasive melanoma if left untreated. It mainly occurs on sun-exposed areas of elderly patients. The lesions can be large and conventional surgery can be difficult, particularly on the face. Recent reports indicate that topical imiquimod 5% cream is effective in the treatment of LM. It may be an alternative when surgery or other classical treatments are not possible in elderly patients. We describe an 80-year-old Caucasian woman with a 10-year history of a histologically verified extensive LM of the face. She was treated with imiquimod 5% cream once daily. After four months it showed complete clinical response. One year after the treatment the patient was still free from recurrence.
