Carcinoma basocelular em localizações incomuns

Abstract

Os autores apresentam cinco pacientes que desenvolveram carcinomas basocelulares em locais incomuns de ocorrência desse tumor. O objetivo é relatar a raridade topográfica da neoplasia cutânea e discutir o conceito de localização incomum para o carcinoma basocelular.

An Unusual Location of Basal Cell Carcinoma: Two Case Reports

“…Epitelyal tümörlerin yaklaşık %65'ini oluşturan BHK en yaygın kutanöz malignitedir (5). Gelişiminden sorumlu etyolojik faktörler; deri fototip I ve II, ultraviyole ışığına uzamış maruziyet, arsenik, kömür katranı gibi kimyasal karsinojenlere maruziyet, kronik ülser veya travma, yanık sonrası gelişen skarlar, radyoterapi öyküsü, immün yetmezlik, aşılar, virüsler, özellikle perianal bölge için HPV, dövmeler, ailesel deri kanseri hikayesi, çocukluk çağında çil oluşumuna yatkınlık, kronik deri irritasyonu, albinizm, kseroderma pigmentozum ve nevoid BHK sendromu gibi kalıtımsal sendromlar, çevresel faktörler, bronzlaşma, ilerlemiş yaş, yüksek yağlı diyet, meslek ve erkek cinsiyeti kapsamaktadır (3-5, 8-10).…”

Múltiplos carcinomas basocelulares na região pubiana em uma paciente fototipo IV: relato de caso

“…1,4 In the last years, in addition to increased incidence due to a greater awareness of the population to seek for a specialist at the slightest sign of cutaneous lesions, as well as more attentive doctors to the diagnosis of the disease, alterations in the presentation of BCC can be observed such as the involvement of areas photoprotected and a higher incidence in females. 5,6 It is estimated an incidence from 10 to 15% of all BCC diagnosed in covered areas and the factors responsible for such anatomic distribution are not yet well elucidated. 6 The unusual sites are: breast, periungal region, palm, sole, buttocks and intertriginous areas (axillae, groin and genitalia).…”

“…6 The unusual sites are: breast, periungal region, palm, sole, buttocks and intertriginous areas (axillae, groin and genitalia). 6,7 A female patient, phototype IV (mullato), aged 62, sought for medical assistance presenting multiple lesions slightly elevated, with clear edges, eryhematous-pigmented, in the pubic region, that had appeared 8 months before. She had no personal or family history of skin cancer or immunodeficiency and no exposure to tar or ionizing radiation.…”

“…7 Despite the characterisitc aspect of the lesions, findings outside the elected sites can make the clinical hypothesis more difficult and retard diagnosis and treatment. 6 In the last years, it has been observed an increase in the number of cases of BCC in women, justifiable by a greater integration of the female sex in the labor market and in activities which before had been considered male activities 5 , at earlier ages and in areas not photoexposed 6,7 . These conditions deserve further studies to better understand the pathogenesis of this tumor.…”
