Pyogenic granulomas (PGs), also known as lobular capillary hemangiomas, are common reactive lesions that are non-neoplastic in nature. While they typically present as isolated lesions, they can rarely develop from preexisting port-wine stains (PWSs). PWS-associated PGs may occur spontaneously but are often linked to pregnancy or prior treatments such as laser therapy, intense pulsed light therapy, or radiotherapy. Here, we report a rare case of a PG arising from a PWS on the parietal scalp of a 27-year-old man with no history of trauma or prior treatment for his PWS. Given the potential for secondary lesion development in PWS, regular monitoring is essential, particularly in patients with associated risk factors.

An auricular pseudocyst is an uncommon, benign cystic lesion that frequently occurs in the auricles of middle-aged male patients, characterized histologically by an intracartilaginous, non-epithelial-lined cystic space. This report presents two cases of auricular pseudocysts successfully treated using deroofing procedures, with excellent long-term outcomes observed at 6-month and 5-year follow-up, respectively. Although various treatment modalities may be employed for these lesions, surgical deroofing is considered a conventional and reliable option that provides low recurrence rates and superior aesthetic outcomes.

A cerebriform connective tissue nevus (CCTN) is a key diagnostic feature of Proteus syndrome (PS), a rare genetic disorder characterized by the abnormal growth of bones, skin, adipose tissue, and other tissues. A plantar CCTN often causes difficulties with shoe fitting and walking. This paper presents a case of PS and the outcomes of debulking surgery for a plantar lesion. A 54-year-old male presented with a large plantar mass on his left foot, which caused problems with shoe fitting. The lesion developed during childhood and progressively worsened into adulthood. A physical examination revealed a typical CCTN with deep grooves and gyrations on the left plantar surface. The patient sought surgery due to difficulty in wearing shoes. Considering the postoperative complications associated with total excision and the potential risks associated with PS, including perioperative morbidities and anesthesia-related challenges, debulking surgery was chosen to reduce the lesion rather than perform a total excision. Staged excisions were performed three times under local anesthesia, with redundant tissue removed, and the wound was primarily closed after each procedure. At the one-year follow-up after the final procedure, the patient could comfortably wear ready-made shoes and exhibited an improved standing posture and reduced walking impairment. Therefore, debulking surgery for a large plantar CCTN can be an alternative to total excision.

A 71-year-old female patient developed cellulitis-like lesions at the burns from moxibustion of the right calf. The lesion was unilateral, a single confluent lesion with swelling and tenderness. Oral antibiotic treatment was performed with a poor clinical response. The patient was hospitalized and received intravenous broad-spectrum antibiotics, but the lesion progressed without improvement. Considering the possibility of erythema nodosum, the prescription was changed to methylprednisolone, and the redness, warmth and swelling improved the day after. A skin biopsy revealed features suggestive of panniculitis
