Rationale:
Extramammary Paget’s disease (EMPD) is a rare skin cancer that commonly occurs in sites rich in apocrine glands, such as perineum, vulva, axilla, scrotum, and penis. On the other hand, condyloma acuminatum (CA; also referred to as anogenital warts) is a common benign neoplasm caused by human papillomavirus. Few cases of coexistent EMPD and CA have been reported because of the rarity of the condition.
Patient concerns and diagnosis:
A 72-year-old man with a genital mass, which appeared to be composed of multiple papillomatous masses, was referred for surgical resection. The lesion was first noticed 6 months previously and grew rapidly. CO2 ablative laser therapy was performed twice at a primary clinic, but the mass recurred.
Intervention and outcomes:
Excisional biopsy revealed the presence of coexistent EMPD and CA. Additional wide excision was performed, and postoperative biopsy confirmed no residual tumor. Two years after surgery, no recurrence had occurred.
Lessons:
CA can co-occur with several types of skin malignancies, and a skin malignancy coexisting with CA is difficult to diagnose visually. Therefore, even if a skin lesion in the genital region is considered to be CA, we recommend punch biopsy before treatment because it can benefit prognosiss.
An 88-year-old man presented with a left temporal pulsatile mass that developed after blunt trauma. Based on suspicion of hematoma, needle aspiration was performed with the removal of approximately 15 mL of blood. No evident improvement was noted, and active arterial bleeding was observed at the needle puncture site. Doppler ultrasonography revealed a “yin-yang” sign, and the mass was diagnosed as a pseudoaneurysm of the left superficial temporal artery. Under general anesthesia, the superficial temporal artery was ligated and the pseudoaneurysm was removed. Superficial temporal artery pseudoaneurysm is a rare facial tumor that generally occurs after blunt trauma. Due to its rarity, pseudoaneurysms are often misdiagnosed as hematoma. The treatment of choice is excision, although endovascular intervention is a potential treatment option. However, when a pseudoaneurysm is small, conservative treatment can be used.
Hidradenitis suppurativa (HS) is a chronic inflammatory condition that is difficult to diagnose, with a period of 10.0± 9.6 years from symptom onset to diagnosis. A 32-year-old Asian man presented with bilateral postauricular abscesses that first appeared 5 years previously. Despite several incisions and drainage, the symptoms only temporarily improved and continued to recur. On physical examination, chronic scars and sinus tracts were observed around the lesion. Postauricular HS was diagnosed, and surgical treatment was performed. We performed a wide excision and reconstructed the defect using a posterior auricular artery perforator-based keystone flap. Histological examination confirmed the diagnosis of HS. The reconstruction was successful, and there was no recurrence for 2 years after surgery. HS is difficult to diagnose without specific attention. Although the postauricular region is not a typical site of HS, it can occur in this area. Therefore, if a patient presents with recurrent abscesses in the postauricular region, HS should be considered. Additionally, if HS is diagnosed in the postauricular region, wide excision with reconstruction using a posterior auricular artery perforator-based keystone flap can lead to a favorable outcome.
In many cases chronic wounds in the lower extremities are extremely difficult to heal because of inadequate blood supply, and when wounds are complicated by osteomyelitis, plastic surgeons and orthopedic surgeons must join forces to facilitate treatment. A 63-year-old man with bone exposure and a peripherally indurated chronic open wound complicated by osteomyelitis of the right distal thigh was admitted to the department of orthopedic surgery at our hospital. He was referred to our department for treatment of the right side chronic open wound. We report our successful experience with a partial biceps femoris muscle transposition flap with fasciocutaneous expanded-keystone advancement flap following wound and bone debridement for the coverage of complex wounds associated with bone infection. The results show two discrete layers of muscle. In patients with chronic osteomyelitis, fasciocutaneous flaps might provide a more effective means of covering full-depth soft tissue defects without donor site morbidity, compared to free flaps.
