Summary: Acquired digital fibrokeratoma is a rare benign fibroepithelial condition, which typically occurs as a solitary asymptomatic nodule in fingers and toes. The authors report the clinical case of a female patient affected by two digital fibrokeratomas in the 4th and 2nd left fingers, respectively.

The authors describe the case of a 75-year-old female patient, bearing a single asymptomatic, nodular lesion of fibroelastic consistency for three years, located on the left hallux. Following surgical excision of the lesion, the pathological examination and immunohistochemistry revealed a superficial acral fibromyxoma. This type of lesion was first described in 2001 and today there are approximately 100 cases in the literature. It is a benign mesenchymal tumor of slow growth, with a predilection for ungual and peri-ungual regions. There are no reports of malignant transformation and recurrence has been associated with incomplete resection.

Melanonychia corresponds to color patterns in the nail plate, ranging from brown to black. It is a diagnostic challenge due to the fact it has several differential diagnoses, including benign and malignant entities. There are no reports of pigmented fibroma of the nail matrix causing striata (or longitudinal) melanonychia. In light of this fact, the authors report a case of melanonychia striata secondary to pigmented fibroma of the nail, with clinical examination and dermoscopic findings suggestive of nodular melanoma.

Pachydermodactyly is a rare, benign and acquired form of digital fibromatosis characterized by the thickening of soft tissues in the lateral regions of the proximal interphalangeal joints, typically of the digiti II, III and IV of both hands. In most cases it is associated with repeated digital microtraumas. The authors of the present article report the case of a 22-year-old patient with a typical clinical presentation of the condition. The treatment with triamcinolone injections led to a partial reduction of the thickening, in addition to hypopigmentation and hyperemia, meaning it was an unfavorable option. Although rare and benign, this typical clinical condition deserves attention, and unnecessary and costly investigations, as well as inappropriate treatments should be avoided.

INTRODUCTION: Acrochordons are very prevalent in dermatological offices and can reach almost 60% of the population over 70. One possible therapeutic approach is contact cryotherapy.
OBJECTIVES: Compare pain tolerance, aesthetic results, and the preference of participants for electrocoagulation or contact cryotherapy techniques in the treatment of acrochordons.
METHODS: Ten participants, with at least four acrochordons each, had their lesions divided into two groups. One group was submitted to electrocoagulation and the other to contact cryotherapy. We measured pain tolerance using the analog pain scale (EAD). The aesthetic result was assessed by visual comparison between the treatment groups in each participant, and the patient’s preference was evaluated by asking the participant objectively.
RESULTS: All points analyzed had statistical significance. The participants gave lower scores in EAD for lesions submitted to contact cryotherapy. The esthetic result evaluated after 30 days was superior in the lesions of the electrocoagulation group. All participants preferred the contact cryotherapy technique.
CONCLUSIONS: Contact cryotherapy is the preferred method with better pain tolerance in treating acrochordons, but the aesthetic result was better with electrocoagulation.

Koenen tumors are nail fibromas included among the main diagnostic criteria of tuberous sclerosis. Elongated and thin papules, firm, with smooth surface and broad base characterize these lesions, which are slightly erythematous and present varying sizes. Koenen tumors commonly affect toenails and result in aesthetic and functional concerns associated with deformities, pain, and bleeding. Several therapeutic options are described for Koenen tumors; however, there is a lack of consensus in the literature regarding standard treatment. We report the case of a patient who underwent surgery with excellent outcomes. Additionally, we discuss the advantages and disadvantages of each therapeutic modality.

Superficial acral fibromyxoma is a rare and benign mesenchymal tumor. It mainly affects middle-aged men; however, it can occur in any gender and age group. It has a slow growth, with a preference for nail and periungual areas.

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.
