Introduction: Tuberous sclerosis is a dominant autosomal genodermatosis, classically characterized by facial angiofibromas, fibrotic plaques, periungual fibromas, leaf-shaped hypochromic maculae and fibrous frontal plaques.
Case report: A patient bore this disease, with Koenen tumors in all nail beds of hands and feet, which were resistant to the conventional treatment — simple excision and electrosurgery. Amputation of the nail beds was performed followed by reconstruction with full thickness skin grafts.
Conclusion: The amputation of the nail apparatus and reconstruction with full thickness skin grafts in aggressive, recurrent or high morbidity cases can be an effective therapeutic option.

O queratoacantoma (QA), apesar de frequente na prática diária, é um tumor que gera questionamentos. O aspecto mais intrigante associa-se à sua posição no limite entre malignidade e benignidade. A abordagem do tumor, bem como sua classificação, é controversa. Na definição da conduta, é importante levar em conta o potencial de transformação para carcinoma espinocelular. Desse modo, a excisão cirúrgica é a terapia de escolha, sempre que possível. Algumas situações merecem atenção adicional, como a imunossupressão associada. Neste artigo, relatamos um caso de QA gigante em um paciente com síndrome da imunodeficiência adquirida tratado com cirurgia micrográfica de Mohs.

Sarcomas são neoplasias mesenquimais malignas, raras, que acometem, principalmente, crianças e adolescentes. O rabdomiossarcoma, subtipo oriundo da musculatura esquelética, é condição incomum em adultos, acometendo sítios de localização não habitual, crescimento rápido e de difícil tratamento. Apresenta-se caso de adulto jovem com nodulação em lóbulo auricular esquerdo, cuja análise histopatológica e imuno-histoquímica confirmou tratar-se de rabdomiossarcoma alveolar, o qual foi conduzido em conjunto com a Oncologia.

Modern hair transplant is constantly evolving. We intend to demonstrate our techniques and methodologies, and especially to describe the dynamics of the entire surgical process of the FUE (Follicular Unit Extraction), technique, from the discussion of the surgical strategy with the patient and evaluation of the donor area to extraction and implantation. The dermatologist must understand the complexity of the procedure and the need for adequate training to achieve a good surgical result.

Hair transplant is a common procedure worldwide, and the method of extracting follicular units is currently the most used. This technique is used not only for androgenetic alopecia but also for other areas such as eyebrows and beard. It is essential to observe the angle of the incisions and implantation of the hairs to conduct the eyebrow transplant so the result is as natural as possible. However, in addition to being rigorous with the design of the shape and position of the eyebrow, care must be taken with the preparation from the receiving site.

Hair transplantation is an option for anyone with Androgenetic Alopecia, including transgender patients who want to align their appearance with their gender identity. Thus, hair transplantation can help transform appearance and boost self-esteem, especially if hair loss is a source of gender dysphoria. We report two cases of hair transplantation in transgender patients with good results, using the Follicular Unit Extraction and Follicular Unit Transplantation techniques. Due to the scarcity of specific articles about hair transplantation in this population, we report these cases for a better understanding of the specific needs of these patients.
