序論：形成外科医は他診療科からリンパ節生検の依頼を受ける機会があるが，生検後の治療にかかわることはほとんどない。そのため，患者の転帰や予後について議論されることが少ない。リンパ節生検患者の転帰と予後について検討した。
 方法：2018年11月から2021年８月までの２年10ヵ月の間に自治医科大学附属さいたま医療センター形成外科で施行したリンパ節生検52症例を対象とした。
 結果：生検したリンパ節の病理組織学的診断結果は，悪性リンパ腫が28例で52症例中最も多かった。52例中14例が死亡の転帰をたどっており，生検が施行された日から死亡までの日数は6～287日（中央値29.5日）であった。
 考察・結論：リンパ節生検患者は急な転帰をたどる場合も少なくなく，早期に確定診断にいたることは，その後の治療，および患者とその家族の心情を考慮すると重要である。そのため，リンパ節生検は依頼診療科と採取部位や適応などを協議のうえ，可及的早期に対応することが望ましいと考える。

 Solitary fibrous tumor (SFT) is a spindle cell neoplasm derived from mesenchymal cells, which is classified as an intermediate malignancy. The cellular variant of SFT has a poor prognosis. Surgical treatment is the first choice. There are several approaches to intraorbital SFT. In this report, we describe two cases of intraorbital SFT treated with different approaches. In the first case, the tumor extended posteriorly beyond the equatorial plane of the eye, and excision was performed using a transcranial approach. In the second case, the tumor was localized anteriorly to the equatorial plane of the eye, and excision was performed using an anterior approach, followed by postoperative irradiation therapy. The tumor was classified as a cellular variant, and histopathological examination showed a partially positive margin and high MIB-1 index. In both cases, there was no postoperative recurrence after approximately 2 years.

 Infections or foreign body reactions following craniotomy can lead to intractable scalp ulcers due to the exposure to artificial materials. Achieving wound closure in these cases is often challenging, involving local flap and free flap transfer techniques. Herein, we describe two cases of intractable ulcers caused by exposure to artificial materials, treated with perifascial areolar tissue (PAT) grafts. Case 1 was a 65-year-old man who underwent craniotomy for cerebral hemorrhage. Case 2 was a 76-year-old man who underwent craniotomy for an intracranial tumor biopsy. Both patients experienced postoperative ulcerations at the wound site. The artificial materials were removed, and PAT grafting was performed. Complete wound closure was achieved in both cases; however, both patients developed depressed deformities. PAT grafting is a relatively minimally invasive and effective treatment for scalp ulcers; nevertheless, careful follow-up is necessary to monitor for potential depressed deformities and ulcer recurrence.

 Labial adhesion is caused by a membrane-like fusion of the labia. This condition occurs mainly in infants and young children, with few reports in adults. In adults, labial adhesion is usually identified when postmenopausal females visit a hospital with complaints of difficulty urinating and abnormal urinary flow. In infants and young children, the condition is typically treated with cleaning of the affected area and application of estrogen-containing ointment. However, surgical treatment is often necessary for postmenopausal labial adhesion. Due to the high recurrence rate after simple incision and suture, surgery involving the use of a local flap, such as Z-plasty, is useful; however, standard methods remain to be established. Herein, we report our experience with two cases of postmenopausal labial adhesion, in which favorable results were obtained after surgery using Z-plasty and Y-V plasty.

 A pseudoaneurysm of the superficial temporal artery results from injury to the arterial intima and media, which is characterized by widening of the vessel. In many cases, pseudoaneurysms occur secondary to trauma or inflammation of the tissues surrounding the arteries. To our knowledge, this is the third case report of a pseudoaneurysm of the superficial temporal artery following a thread-lifting operation. A 42-year-old woman sustained an injury to the left superficial temporal artery during a thread-lifting procedure, which resulted in pseudoaneurysm formation. The number of thread-lifting operations is expected to increase in the future with the increasing popularity and awareness of cosmetic medicine; therefore, it is important for surgeons to be well-acquainted with the anatomy of the facial arteries. The development of novel and improved methods for thread-lifting operations is warranted to avoid unexpected complications.
