- Bleomycin-induced flagellate hyperpigmentationPublication . Resende, C; Araújo, C; Gomes, J; Brito, CBleomycin is a chemotherapeutic agent used in the treatment of different tumours. It has several side effects, including flagellate hyperpigmentation, which is a unique and a well-documented side effect of bleomycin therapy. We report a case of a 23-year-old woman with a personal history of ovarian dysgerminoma, who developed flagellate hyperpigmentation on trunk after bleomycin therapy.

- Late onset Ito's nevusPublication . Resende, C; Araújo, C; Vieira, AP; Brito, CDermal melanocytoses include a variety of congenital and acquired melanocytic lesions characterised by the presence of multiple spindle-shaped dendritic melanocytes in the dermis. These lesions are commonly found in the skin of Asians, but they can also appear in Caucasians. The Mongolian spot, nevi of Ota and Ito are the most common morphological forms. We report a case of a 24-year-old Caucasian woman presented with a 10-months history of progressive darkening of the right side of her upper back. Cutaneous examination revealed a macular blue-grey hyperpigmentation of the right side of her upper back. Biopsy specimen from the macule showed multiple darkly pigmented, spindle-shaped dendritic melanocytes in the superficial dermis, interstitially arranged between collagen bundles. The diagnosis of nevus of Ito was established. Our patient is maintaining vigilance in dermatology consultation.
- Rapidly lethal dermatomyositis associated with cutaneous lymphangitis carcinomatosaPublication . Resende, C; Araújo, C; Duarte, ML; Brito, CA 70-year-old woman with a recent diagnosis of dermatomyositis (DM) presented to the dermatology department for study of a probably paraneoplastic syndrome. On examination, we observed discrete, indurated, reddish, painful plaques and nodules on her abdomen and both thighs. A cutaneous biopsy from an abdominal nodule, performed as part of the paraneoplastic workup, was suggestive of cutaneous lymphangitis carcinomatosa, secondary to unknown malignancy. An extensive investigation to locate the site of the primary tumour revealed no specific findings. A course of palliative chemotherapy with cisplatin and 5-fluorouracil was then given, but the patient's condition deteriorated and 6 months after her initial observation the patient died. We describe this case because, to our knowledge, the association between DM and cutaneous lymphangitis carcinomatosa has not been described yet in the literature and to highlight that, DM can be a rapidly lethal disease.
- Schimmelpenning syndromePublication . Resende, C; Araújo, C; Vieira, AP; Ventura, F; Brito, CSchimmelpenning syndrome (SS) includes an organoid nevus that follows the lines of Blaschko and defects of brain, eyes, bones, or other systems. We report a case of a 3-month old female infant, who presented with several thin plaques, with irregular borders, yellowish color, which had a verrucous appearance, following the lines of Blaschko, mainly occupying the left side of posterior trunk, the left face, the right side of the anterior trunk, and the right upper limb. These plaques had been present since birth. In addition, she had a flat salmon to yellow nevus on the left parietal and temporal region of the scalp, with a bald patch. She was diagnosed after birth with an interauricular communication. The skin biopsy from the lesion of the right arm revealed an epidermal nevus that occupied the epidermis completely. Routine and other complementary laboratory blood tests, including platelet count, thyroid function tests, 25-hydroxy-vitamin D, parathyroid hormone, and plasma and urinary levels of calcium and phosphorus were negative. Cerebral magnetic resonance and renal ultrasound were normal. The diagnosis of SS was established. She is being followed in the clinics of Dermatology, Cardiology, Pediatrics, and Pediatric Neurology. We report this case to point out the importance of investigating patients with epidermal nevus to identify associated conditions.
