RESUMO
@#<p style="text-align: justify;"><strong>INTRODUCTION:</strong> Trichoepithelioma is a benign hamartoma which may exhibit similar clinical and histopathological features with basal cell carcinoma. Since prognosis is dissimilar, differentiating between them is important. Literature reveals fifteen reports of malignant transformation of multiple trichoepitheliomas into basal cell carcinoma, with none in the local setting. In Brooke-Spiegler syndrome, the incidence rate of malignant transformation of benign neoplasms has been reported in 5-10 % of patients.</p><p style="text-align: justify;"><strong>CASE REPORT:</strong> A 53-year-old Filipino-American female presented with multiple discrete to coalesced, well-defined, skin-colored to hyperpigmented, smooth, dome-shaped, rubbery papules and nodules on the face since childhood. Throughout the years, lesions increased in number and size and spread to the scalp, chest, abdomen, back, upper and posterior right thigh. Some developed ulceration, telangiectasia and pigmentation.</p><p style="text-align: justify;">Chest radiography, radiographs of the jaw, whole abdominal ultrasound, cranial CT scan, ophthalmology and otorhinolaryngology assessments were normal. Based on clinical and histopathologic findings, the final diagnosis was Brooke-Spiegler syndrome with transformation into basal cell carcinoma. Carbon dioxide (CO2) laser was used to excise large and ulcerated lesions with good cosmetic results.</p><p style="text-align: justify;"><strong>CONCLUSION:</strong> A case of a Filipino-American adult female diagnosed clinically and histologically with Brooke-Spiegler syndrome with transformation into basal cell carcinoma was presented. Given the similarities in clinical and histopathologic features of trichoepithelioma and basal cell carcinoma, accurate diagnosis should be made because of their difference in prognosis. The use of an acceptable treatment modality such as carbon dioxide (CO2) laser in this case is an important emerging fi eld of study.</p><p style="text-align: justify;"><strong>KEYWORDS:</strong> trichoepithelioma, basal cell carcinoma, Brooke-Spiegler syndrome, malignant transformation, carbon dioxide laser</p>

@#INTRODUCTION: Exfoliative dermatitis is a potentially life- threatening inflammatory reaction that poses a significant risk for morbidity and mortality. Several underlying etiologies of this dermatologic condition include pre-existing dermatoses, drugs and malignancy. Although it is a common disease entity, local studies on exfoliative dermatitis published in literature are very limited. OBJECTIVE: The primary objective of this study is to determine the epidemiological profile of patients with exfoliative dermatitis diagnosed at University of Santo Tomas Hospital Dermatology department from January 2008 to December 2012. METHODS: Inpatient and outpatient clinical records of patients diagnosed and treated as exfoliative dermatitis were retrieved. The prevalence, clinical presentation, history of previous dermatoses or use of any drugs/topical medications, family history and accompanying systemic symptoms were reviewed and analyzed. RESULTS: A total of 67 patients were included in this retrospective study. The prevalence among patients with exfoliative dermatitis in this study was computed at 1 per 1000 dermatologic patients. The highest number of cases belonged to the group aged seventy-one to seventy-nine (25.4%) with a mean age of 56.62 years. There was a male predilection (65.7%). Clinical presentation of patients included pruritus, generalized scaling and erythema, accompanied by bipedal edema (41.8%), chills (22.4%), fever (T ≥ 38 °C), lymphadenopathies (6%) and joint pains (4.5%). Several etiologic factors of exfoliative dermatitis recorded were: pre-existing dermatosis (67.2%), idiopathic or undetermined causes (19.4%), drug-induced (10.4%) and malignancy (3%). CONCLUSION: Exfoliative dermatitis is a condition more commonly found in the older age group. Pre-existing dermatoses, drugs and malignancy are etiologic factors. The most common pre-existing dermatosis causing exfoliative dermatitis in this study is psoriasis while the most implicated drug is allopurinol.
