Abstract
Cutaneous syncytial myoepithelioma (CSM) is a recently recognized variant of myoepithelial neoplasms. CSM is characterized by an intradermal syncytial proliferation of spindled, ovoid, and histiocytoid cells. Immunohistochemically, tumor cells usually show strong positivity for S-100 and EMA. Here, we report a case of CSM in the thigh of a 51-year-old Japanese woman. Histopathological findings showed a sheet-like growth of ovoid cells and histiocytoid cells with an eosinophilic syncytial cytoplasm, and adipocytic metaplasia was widely observed in the tumor. Immunohistochemical staining revealed a diffuse strong pattern for EMA, smooth muscle actin (SMA), and HHF35 and variable positivity for S-100 protein and p63 in ovoid and histiocytoid cells without significant mitotic figures or pleomorphism. In addition, EWSR1-PBX3 gene fusion, which is characteristic of CSM, was observed in the tumor. Based on these findings, we diagnosed the patient as having CSM. Our case suggests that CSM could show extensive adipocytic metaplasia, which could make its histopathological diagnosis challenging. This article is protected by copyright. All rights reserved.

Abstract
Sclerodermatous graft-versus-host disease (GvHD) is one of the many clinicopathological variants of chronic GvHD. One of the rarest forms of this variant is GvHD-associated angiomatosis (GvHD-AA). We describe the case of a 62-year-old male with sclerodermatous GvHD who presented, in consecutive years, two different lesions that showed characteristics of GvHD-AA. The first lesion fitted perfectly with the previously known features of this rare entity. However, the second lesion was more interesting, as the angiomatoid lesion was surrounded by newly appeared adipocytes, something not previously described. The appearance of this peculiar adipose tissue may be explained as related to an important dermal atrophy, as a concomitant appearance of a lipomatous nevus and GvHD-AA, or, finally, as mature adipose tissue related to a previous inflammatory process, that is, lipomatous metaplasia. Both lesions were diagnosed as GvHD-AA, and the second one was considered to be associated with dermal lipomatous metaplasia. We also considered whether hypoxia could be related to both lesions. In the present report, we review previously published cases of GvHD-AA and discuss the different hypotheses that could explain the appearance of metaplasia associated with the second lesion.

Abstract
ABSTRACT Lipomatous metaplasia has been rarely reported in both neoplastic and inflammatory dermatological disorders. Most neoplastic cases show the lipomatous change within the tumor silhouette, but band-like lipomatous metaplasia in the dermis under tumors has not been well-described. The aim of this study was to reveal the characteristics and relationship of intradermal band-like lipomatous metaplasia and coexisting skin tumors. A total of 20 cases with intradermal band-like lipomatous metaplasia were retrieved from 10,992 archive cases between April 1997 and March 2020 at Hyogo Cancer Center, and subjected to a detailed clinicopathologic analysis. Nine (45%) patients had superficial variant basal cell carcinoma as a coexisting neoplasm. Eight (40%) patients had squamous cell carcinoma, 5 of which were in situ. The remaining 3 (15%) cases were invasive extramammary Paget disease. All 20 cases showed at least one of 3 signs of tumor regression, namely, partial loss of overlying neoplasia, significant inflammatory infiltrate under the tumor, and fibrosis around the tumor. We concluded that intradermal band-like lipomatous metaplasia could be seen in association with the regressing process of cutaneous superficially-spreading neoplasms.

Abstract
Lipoma arborescens, a rare benign intra-articular lesion, is characterized by lipomatous proliferation of the synovium in which the subsynovial tissue is replaced by mature adipocytes. Subdeltoid bursa is a rare location for lipoma arborescens, and only a few cases have been reported in the literature. This article reports 2 cases of subdeltoid lipoma arborescens combined with rotator cuff tears, and the possible relationships between subdeltoid lipoma arborescens and rotator cuff tears are discussed. The intra-articular villous proliferations on fat-suppressed T2-weighted magnetic resonance imaging appeared as yellowish-white lipomatous villous proliferations on arthroscopy, and finger-like lipomatous proliferation of the synovium, where the subsynovial connective tissue is replaced by mature adipocytes, on histology. Although further evidence would be necessary, the bony proliferations, in addition to bone-to-bone abrasion and inflammatory processes, may contribute to the relationship between subdeltoid lipoma arborescens and rotator cuff tears. Because this is a rare disease in a rare location, no established treatment guidelines are available for lipoma arborescens in subdeltoid bursa. For the current patients, arthroscopic excision of the lipoma arborescens and concomitant rotator cuff repair were prescribed after more than 6 months of conservative management. All patients had symptom relief and were satisfied with their results. Paying special attention to the radiologic and arthroscopic characteristics of the lipoma arborescens will help physicians and surgeons to achieve a more accurate diagnosis and effective treatment strategy, especially in patients with concomitant rotator cuff tears.
