DNA-virus, which belongs to the papillomavirus group, causes Condylomata acuminata. In children under 3 years of age, transmission tends not to be due to sexual abuse but rather vertically. There is no consensus for the treatment of anogenital warts in children. The chosen method is individualized for each patient, preferring less traumatic treatments, with fewer sequelae. Although there are still some restrictions on the imiquimod use in children under 12, studies have already shown this therapy’s success in this age group. We report a case treated with 5% imiquimod cream with the resolution of pre-existing lesions.

Acral amelanotic melanoma is rare and can mimic many entities, such as eccrine poroma, squamous cell carcinoma, plantar wart, and chronic ulcers. Due to the variety of possible differential diagnoses, it is a challenging and frequently late diagnosis. Dermoscopy features can help in early diagnosis. The dermatologist should keep this diagnosis in mind when faced with a pink, progressively growing, irregularly shaped lesion, mainly if located on the hands and feet.

Aneurysmal dermatofibroma (ADF) is a rare benign tumor originating in the dermis. It is most common in the lower limbs of women over 30 years. Its etiology is unknown, and histopathological examination confirms the diagnosis. This paper presents a case of ADF with an exuberant presentation in a young female patient with a pedunculated tumor in the right pretibial region, measuring 12 cm in greatest diameter. This report aims to demonstrate an infrequent variant of dermatofibroma with significant growth and emphasize the importance of lesion excision and follow-up because of the high recurrence rate.
