Scalp Metastasis from Follicular Hürthle-Cell Carcinoma of the Thyroid Challeng...
Tavares-Bello, Rui; Tavares-Bello, Carlos; Fernandes, Sónia; Serra, Carlos; Tellechea, Óscar; Garcia, HelenaOverall, skin metastases from internal malignancies are a rare event, ranging from 0.9% to 4.4% in large autopsy studies and reaching 9% in large series of patients. Skin metastases from thyroid carcinoma are even rarer and, among them, follicular carcinomas have seldom been reported in this context, far less so than papillary and medullary carcinomas. A 57-year-old Caucasian male presented with an angioma-like...
Psychological Evaluation in Rosacea Patients: A Case- Control Study using Sympt...
Tavares-Bello, Rui; Torres, NunoBackground: Rosacea, a prevalent chronic facial skin condition, is classically referred to as a “psychodermatosis”, in that psychological factors are relevant both in its initiation and course. Rosacea patients have been described as immature, anxious, with diminished self-esteem and with feelings of guilt and shame, or as psychoneurotic, with hysterical or obsessive compulsive configurations.Objective: In this...
Desmoplastic Trichilemmoma arising on a Nevus Sebaceous of the Scalp
Tavares-Bello, Rui; Tellechea, Óscar; Fernandes, SóniaOriginally described by Jadassohn in 1895, it was not until 1932 that the term “nevus sebaceous” was introduced by Robinson. It is a prevalent benign congenital hamartoma that classically evolves through discrete phases of growth and that, from the 4th to the 7th decade of life, can give rise in approximately 10 to 30% of cases to several epithelial neoplasms. Very seldom reported in this context, trichilemmoma...
BLASCHKOLINEAR LICHEN NITIDUS IN A PATIENT WITH COMMON VARIABLE IMMUNODEFICIENCY
Tavares-Bello, Rui; Tellechea, ÓscarLichen Nitidus is a chronic idiopathic immunologically-driven dermatosis that is characterized on the clinical domain by shiny, flesh-colored micropapules and, pathologically, by a lymphohistiocytic dermal infiltrate with hydropic degeneration of the basal layer or, on occasions, inflammation with granulomatous features. The infiltrate fulfills and distorts the papillary dermis, compress the overlying atrophic ...
PHEOCHROMOCYTOMA AND NEUROFIBROMATOSIS 1
Tavares-Bello, Rui; Marcelino, Mafalda; Nobre, Ema L.; Lopes, Luís; Lopes, Carlos; Jácome de Castro, JoãoIntroduction: Pheochromocytomas are tumours arising from chromaffin cells in the sympathetic nervous system. Clinical manifestations are protean, function of the variable secretory profile of several compounds including catecolamines, neuropeptides and other vasoactive molecules. Neurofibromatosis I (von Recklinghausen`s disease), a prevalent autosomal dominant disorder, is the most prevalent type among the neu...
ERUPTIVE VELLUS HAIR CYSTS
Tavares-Bello, Rui; Tellechea, ÓscarThe case of a 6 year old Caucasian male bearing, for the last 12 months, asymptomatic nondescript, flesh colored papules on his anterior thorax and arms is reported. Upon pathological examination, the diagnosis of Eruptive Vellus Hair Cysts was confirmed. A brief revision of this entity, as well as its nosographic framing within the cyst-like developmental skin abnormalities is done.; É apresentado caso de euro...
PARAGANGLIOMA AND ANGIOEDEMA
Tavares-Bello, Rui; de Castro, João Jácome; Santana, Amândio; Palos, Carlos; e Costa, Garcia; Galvão-Teles, A.Paragangliomas or extra-adrenal pheochromocytomas are rare tumors that arise from chromaffin tissues and tend to occur either sporadically or in the context of complex genetic disorders. They are clinically heterogeneous in nature - symptoms deriving either from the secretory profile of the tumor or from the mass effect of the neoplasm. Dermatologic symptoms are quite seldom described in the literature and have...
NAIL – PATELLA SYNDROME
Tavares-Bello, Rui; Baptista, Juliana; Silvério, Cristina; Araújo Pinheiro, LuisNail-Patella Syndrome (OMIN 161200) (Hereditary Onychodysplasia), first reported by Chatelain in 1820, is a rare polymalformative syndrome that affects tissues of both ecto and mesodermal origin. It is an inherited disorder, transmitted as an autosomal dominant trait, having the responsible gene been mapped to 9q34 and further characterized as encoding for a LIM-homeodomain protein that plays a pivotal role in ...
