An umbilical polyp is a rare congenital lesion and it represents one of the developmental anomalies of omphalomesenteric duct remnants. Clinically, an umbilical polyp presents as a red, firm and round tumor with mucoid and sometimes bloody secretions. Umbilical polyps can be mistaken clinically for other umbilical disorders such as umbilical granulomas and granuloma pyogenicum. Hisopathologically, the umbilical polyp is usually composed of small intestinal mucosa or ectopic gastrointestinal mucosa. Herein, we report on two cases of umbilical polyps: one umbilical polyp was composed of small intestinal mucosa and the other consisted of gastric mucosa. (Korean J Dermatol 2010;48(11):1031∼1033)

Acquired lymphangioma circumscriptum of the vulva is a rare benign disease that arises from obstruction of pelvic lymphatic drainage. It most commonly occurs due to surgery, lymphadenectomy and/or radiotherapy for cervical cancer and it may also result from treatment of other tumor or non-neoplastic diseases such as Crohn`s disease or tuberculosis. Epidermal reactive changes due to recurrent infections or stimuli occur in some cases and the vulva lesions can mimic condyloma acuminatum or other viral or fungal infections. Herein we describe a case of acquired lymphangioma circumscriptum of the vulva that mimicked condyloma acuminatum and this all presented 13 years after surgery for cervical cancer in a 71 year old woman.

Background: Dermoscopy is a noninvasive magnification technique that increases the diagnostic accuracy of clinical evaluation by a dermatologist. The characterization of Spitz nevus via dermoscopy is useful for dermatologists in the differential diagnosis of skin tumors. Objective: The purpose of this study was to investigate the dermoscopic features of Spitz nevus in Koreans. Methods: We examined 18 patients with Spitz nevus using dermoscopy. We determined the frequency of specific features revealed by dermoscopy across the single center 15 Korean patients. Results: A total of 21 of Spitz nevi were observed in 18 patients. The common features of Spitz nevi revealed by dermoscopy were regular homogeneous pigmentation (38.1%), a typical pigmented Spitzoid pattern (28.6%), irregular homogeneous pigmentation (23.8%), regular streaks (23.8%), irregular streaks (23.8%), a superficial black network (23.8%), and a nonpigmented typical Spitzoid pattern (19.0%). Conclusion: Dermoscopy revealed specific features of Spitz nevus that can be utilized to evaluate and diagnose the lesions. (Korean J Dermatol 2018;56(1):17∼23)
