Imaging Findings of Soft Fibroma of the Nipple: Two Case Reports

Soft fibromas are benign skin lesions that primarily occur in the neck, axillae, and groin locations. The occurrence of soft fibroma lesions in the nipple is extremely rare. Herein, we present two cases of soft fibroma of the nipple, which occurred in a 51-year-old woman (Case 1) and a 32-year-old woman (Case 2). The mammographic and ultrasonographic features of each case are described in this report. Mammography revealed an oval-shaped isodense mass in Case 1 and an irregular-shaped isodense mass in Case 2. On ultrasonography, Case 1 showed an oval-shaped hypoechoic mass with increased vascularity, whereas Case 2 presented a microlobulated, irregular-shaped, iso- to hypo-echoic mass with subtly increased vascularity at the stalk. In both cases, surgical excision was performed and pathological examination revealed soft fibroma.

Extensive Tuberculous Lymphadenitis Mimicking Distant Lymph Node Metastasis on F-18FDG PET/CT in a Patient with a History of Malignant Melanoma

18-Fluoredeoxyglucose position emission tomography and computed tomography (F-18FDG PET/CT) scanning has been useful in the evaluation of malignant disorders and has been extensively used in cancer screening.1 However, F-18FDG uptake was not found to be specific for cancer diagnosis. Here, we describe increased F-18FDG uptake on PET/CT caused by extensive tuberculous lymphadenitis in a 62-year-old woman with malignant melanoma.

Traumatic Dissection of Subcutaneous Fatty Tissue: Ultrasonographic Findings and Treatment

PURPOSE: To evaluate the imaging findings of a traumatic dissection of subcutaneous fatty tissue and the treatment. MATERIALS AND METHODS: Fifteen lesions from 13 patients treated by sonography were investigated in our study. The lesions were treated by aspiration only, aspiration followed by steroid injection, and by surgical procedure. Based on the treatment, five factors such as location, size and extent of the lesions, nature of the contents, and treatment effectiveness were assessed. RESULTS: A total of 6 lesions in the thigh, 4 in the leg, 3 in the knee, and 1 each in proximal forearm and flank. All lesions were found in subcutaneous fatty tissue with an average size of 8.9 cm. The nature of the contents was serous (n = 2), hemorrhaging (n = 9), and an abscess (n = 1). Without treatment, three lesions disappeared. Five of the 7 lesions vanished after being treated by aspiration. Only one out of three lesions disappeared when they were treated by steroid injection after aspiration. The three hemorrhaging lesions disappeared after operation, but one serous lesion remained. CONCLUSION: Dissection of subcutaneous fatty tissue represents a cystic mass with serous fluid or hemorrhage. The effectiveness of lesion treatment may relate to the location, size, and content of the lesion.

Inflammatory Myofibroblastic Tumor of the Breast: A Case Report

An inflammatory myofibroblastic tumor is an uncommon type of tumor composed of spindle-shaped myofibroblast admixed with mature plasma and inflammatory cells. It is most common in the lungs and in various organs; however, a few cases of inflammatory myofibroblastic tumor of the breast have been reported in the literature. To date, there are no typical radiologic findings but an ill-defined marginated mass which was a suspicious malignancy has been reported in the literature. Here, we describe the mammographic and ultrasonographic findings of a case of an inflammatory myofibroblastic tumor of the breast with a spiculated margin which was strongly suspect as being a malignancy in a 36-year-old woman.
