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.

Glomus tumors (GTs) are rare benign vascular neoplasms that predominantly occur in the subungual region of the digits. However, these neoplasms have also been reported in other anatomical locations. Extradigital GTs often present in atypical locations with unconventional symptoms, posing potential diagnostic challenges for clinicians. Herein, we present a recent case of an extradigital GT found in the forearm of a 76-yearold male patient that exhibited intraoperative features similar to those of a nerve sheath tumor or intravascular tumor, further underscoring these diagnostic challenges. This report highlights the pivotal role of frozen section pathology in diagnosing and managing this atypical lesion, thereby facilitating optimal patient care.
