Carcinoma basocelular tratado con HeberFERON, seguimiento clínico, histológico y ecográfico. Reporte de caso / Basal cell carcinoma treated with HeberFERON, clinical, histological and ultrasound follow-up. Case report

RESUMEN Fundamento: El carcinoma basocelular es el cáncer de piel no melanoma más frecuente, es un tumor de invasión local y crecimiento lento, su incidencia está incrementándose y esto requiere métodos diagnósticos y terapéuticos eficaces, accesibles y rápidos. La ecografía cutánea es una técnica diagnóstica no invasiva que utiliza las propiedades físicas del ultrasonido para el estudio de la piel. Objetivo: Describir el caso de una paciente con carcinoma basocelular en borde del pabellón auricular derecho tratado con HeberFERON y seguimiento con ecografía cutánea. Presentación de caso: Paciente femenina de 60 años con carcinoma basocelular en borde del pabellón auricular derecho, al cual se le aplicó tratamiento con HeberFERON con respuesta completa al eliminar el tumor, lo que se comprobó con la clínica, la histopatología y la ecografía cutánea. Conclusiones: La ecografía cutánea permitió visualizar en tiempo real el tamaño y profundidad del tumor en la piel, asimismo fue útil para confirmar la desaparición de la lesión luego del tratamiento con el HeberFERON.

ABSTRACT Background: Basal cell carcinoma is the most frequent non-melanoma skin cancer, it is a locally invasive and slow growing tumor, its incidence is increasing, so requires efficient, accessible and rapid diagnostic and therapeutic methods. Skin ultrasound is a non-invasive diagnostic technique that uses the physical properties of ultrasound to study the skin. Objective: To describe a patient´s case with basal cell carcinoma on the border of the right auricular pavilion treated with HeberFERON and follow-up with skin ultrasound. Case presentation: 60-year-old female patient with basal cell carcinoma on the edge of the right auricular pavilion, treated with HeberFERON with a complete response after eliminating the tumor, it was verified with the clinic, histopathology and skin ultrasound. Conclusions: The skin ultrasound allowed to visualize in real time the size and depth of the skin tumor, it was also useful to confirm the disappearance of the lesion after the treatment with HeberFERON.

Wide area digital dermoscopy applied to basal cell carcinoma

Abstract In situations in when a dermoscopic record of a large lesion is desirable, the resulting images are usually restricted to a small field of view due to the limited diameter of dermatoscope lenses. This limitation often produces several photographs separately, thus losing the possibility of a single-image global evaluation. In these case reports, we show examples of a recently published image montage technique called Wide Area Digital Dermoscopy, in this case, applied to basal cell carcinomas.

Periungual basal cell carcinoma

Abstract: Periungual basal cell carcinoma is rare and needs to be differentiated from other common diseases that affect this region. Several factors are associated with the development of this tumor, and sun damage seems to play an important role in its pathogenesis. Dermoscopy of clinically indolent lesions on the nail unit can shorten the diagnostic process and avoid destructive treatment and functional damage.

Dermatoscopy-guided therapy of pigmented basal cell carcinoma with imiquimod

Abstract BACKGROUND: Dermatoscopy is a non-invasive diagnostic tool used to examine skin lesions with an optical magnification. It has been suggested as a useful tool for monitoring therapeutic response in lentigo maligna patients treated with imiquimod. OBJECTIVE: To examine the accuracy of dermatoscopy as a tool to monitor the therapeutic response of pigmented basal cell carcinoma treated with imiquimod. METHOD: The authors designed a prospective study. Patients with pigmented basal cell carcinoma were included and data regarding the dermatoscopy features were collected following the Menzies criteria, prior to initiating the imiquimod treatment. Subsequent dermatoscopic evaluations were performed at weeks 4 and 8, following imiquimod discontinuation. RESULTS: Twenty lesions were included. The most common pigmented dermatoscopy features were large blue-grey ovoid nests (80%), followed by blue-grey globules (50%) and leaf-like areas (30%). No spoke wheel areas were observed. In 17 out of 20 patients, a response was noted during the first evaluation at 4 weeks, while the clearance was noted at the second check-up after 8 weeks. In two patients, the clearance was found at the initial evaluation at 4 weeks, while in one patient, the response remained unchanged. Blue-grey globules were the fastest to exhibit clearance (50% at week 4), followed by leaf-like areas (15%) and large blue-grey ovoid nests (6.25%). CONCLUSION: According to our results, dermatoscopic evaluation enhances the accuracy in the assessment of the clinical response to imiquimod in pigmented basal cell carcinoma.

Current views and personal experience regarding primary extraocular malignant tumours

This paper includes discussion of current clinical and therapeutic aspects of more common of the malignant tumors of the eyelid, the conjunctivocornea, and the lacrimal system. In the eyelid, 85-95% of the malignant tumors are basal cell carcinomas and only 5% are squamous cell carcinomas; in the conjunctiva, this ratio is almost completely reversed. However, it appears from the few available reports that the relative incidence of these tumors may not follow this pattern in Pakistan. Malignant melanoma, sebaceous carcinoma, intraepithelial neoplasia and adenocarcinoma also receive appropriate comments. It is interesting that a Pakistani author published the first detailed report of an adenocystic carcinoma of the lacrimal sac and duct in the world literature. Also in Pakistan intraepithelial neoplasia of the conjunctiva, usually a tumor found in adults and the elderly, may be seen in children. Routinely, the sebaceous carcinomas require more extensive procedures, but in one patient cure followed adequate local excision of a sebaceous carcinoma of the tarsus in early stages
