Diagnosis and Preoperative Evaluation of Subungual Glomus Tumors Using Ultrasound

Subungual glomus tumors are benign neoplasms that arise from the neuromyoarterial apparatus. They present with various clinical symptoms such as localized pain, tenderness, and sensitivity to temperature change and can be palpated as a nodule or mass on physical examination. Pressure erosion can be seen at adjacent bones on radiography. However, in most cases, the tumors are too small to be inspected and located under the nail plate, which makes correct diagnosis and complete excision very difficult. Incomplete removal can cause recurrence or deformity to the residual nail, whereas extensive removal can cause trauma or deformity to the nail plate. Thus, correct differential diagnosis and preoperative evaluation of the location and extent of the tumor are very important. Here, we report 2 cases that were diagnosed and preoperatively evaluated using ultrasound.OAIID:oai:osos.snu.ac.kr:snu2014-01/102/2008000790/5SEQ:5PERF_CD:SNU2014-01EVAL_ITEM_CD:102USER_ID:2008000790ADJUST_YN:NEMP_ID:A079501DEPT_CD:801CITE_RATE:0FILENAME:dx preop eval of subungual glomus tumor.pdfDEPT_NM:의학과SCOPUS_YN:NCONFIRM:

Squamous Cell Carcinoma and Bowen Disease in Nail Apparatus

Squamous cell carcinoma of the nail apparatus is a rare phenomenon. Because of its indolent course and similarpresentation to other benign conditions, correct diagnosis in the early stages is practically difficult. We here reporttwo cases of periungual squamous cell carcinoma and squamous cell carcinoma in situ (Bowens disease). Thesecases emphasize the importance of extra vigilance and high suspicion when facing intractable atypical lesions on thefingers. Repetitive biopsy with exploratory nail plate extraction should be considered to acquire appropriatespecimens, which is critical for early and correct diagnosis.N
