Benign lymphangiomatous papules of the skin are considered reactive lymphatic proliferations either caused by disruption of the lymphatic flow or tissue damage produced by operation or radiation therapy. We report a 72-year-old woman with umbilical papules and vesicle-like lesions that led to the diagnosis of a large ovarian fibroma. Histologic study revealed dilated lymphatic spaces manifesting an anastomosing and branched pattern in the papillary and reticular dermis dissecting collagen bundles. The vessels were lined by plump endothelial cells with foci of intravascular papillary endothelial cell hyperplasia. After the ovarian fibroma was removed by laparotomy, umbilical lesions almost disappeared, leaving small flesh-colored papules. A periumbilical dermatosis may herald certain intra-abdominal diseases including those of neoplastic derivation. A heightened awareness of this association may lead to an early diagnosis with a potential for improved patient outcome. Benign lymphangiomatous papules have not been previously described in association with an untreated tumor, without previous operation or radiotherapy. This case advocates for disruption of the lymphatic drainage as the probable pathogenetic mechanism.
皮肤良性淋巴管瘤性丘疹被认为是由淋巴液流动中断或手术或放射治疗引起的组织损伤导致的反应性淋巴增生。我们报告了一名72岁女性,其脐部出现丘疹和水疱样病变,最终诊断为巨大卵巢纤维瘤。组织学研究显示,扩张的淋巴管腔在乳头层和网状真皮中呈吻合和分支状,分割胶原束。血管内衬有丰满的内皮细胞,伴有血管内乳头状内皮细胞增生灶。经剖腹手术切除卵巢纤维瘤后,脐部病变几乎消失,仅留下小的肉色丘疹。脐周皮肤病可能预示着某些腹腔内疾病,包括肿瘤性疾病。提高对这种关联的认识可能会导致早期诊断,从而有可能改善患者的预后。良性淋巴管瘤性丘疹此前尚未被描述与未经治疗的肿瘤相关,且无先前手术或放疗史。该病例支持淋巴引流中断作为可能的发病机制。
