“…MRI is the preferred method to visualize nuchal-type fibroma and its components and borders. Previously published MRI of nuchal-type fibromas demonstrated masses with a low or mild signal intensity (6)(7)(8). The present MRI revealed a mass that displayed mixed signal intensity on T1-and T2-weighted images, which was a prominent difference compared with previously reported findings.…”

“…In the majority of cases, the lesion is solitary; only a small number of cases involving multiple lesions have been reported (2)(3)(4). Extranuchal sites include the extremities, lumbosacral area, buttocks and face (4)(5)(6)(7)(8)(9)(10)(11). The tumor typically presents between the third and fifth decades of life, but lesions have additionally been reported in patients aged 3-74 years.…”

Abstract. Nuchal-type fibroma, initially described in 1988 by Enzinger and Weiss, is a rare clinical entity associated with distinct subcutaneous and dermal fibrous tissue proliferation. The etiology of nuchal-type fibroma largely remains to be elucidated. Typical characteristics of this entity include hypocellular, haphazardly arranged collagen with entrapped adipose tissue, paucity of elastin and entrapped small nerves, on which the pathological diagnosis is based. Magnetic resonance imaging (MRI) is the preferred imaging modality for the detection of nuchal-type fibroma, due to its superior soft tissue resolution and multi-planar capabilities. The present study presents the unique findings of a nuchal-type fibroma arising in the shoulder of a 48-year-old man. Distinct features of the nuchal-type fibroma in the present case included hyperintensity on T1-and T2-weighted MRI. Microscopic examination revealed marked mucoid tissue degeneration. To the best of our knowledge, this is the first case report of nuchal-type fibroma presenting with these distinct features. The present findings may therefore assist with the general and differential diagnosis of nuchal-type fibroma.

“…This tumor is a dermal spindle cell tumor of intermediate malignancy characterized by a slow evolution, a significant risk of local recurrence and a low rate of metastasization [1]. DFSP typically presents during early or middle adult life in all parts of the body, although more frequently on the trunk, extremities, and head and neck [1]. Its location in the breast is extremely rare and very few cases have been reported in the literature.…”

Dermatofibrosarcoma presenting as a nodule in the breast of a 75-year-old woman: a case report

et al. 2011

IntroductionDermatofibrosarcoma protuberans is a rare neoplasm of soft tissues and its location in the breast is extremely uncommon. Confusion is possible with other primary breast lesions.Case presentationA 75-year-old Caucasian woman presented with a mass in her left breast 21 years after being diagnosed with invasive ductal carcinoma of the right breast, treated by a right mastectomy and axillary dissection followed by radiotherapy and breast reconstruction. Mammography revealed a dish-shaped skin nodule formation in the upper outer quadrant of her left breast. Echography confirmed the presence of a lesion measuring 1.4 × 0.8 cm. Based on imaging, the diagnosis was a probable angiosarcoma. Due to the presence of a pacemaker for cardiac arrhythmia and full anticoagulation therapy for a pulmonary embolism, magnetic resonance imaging and a biopsy were not done. We proceeded directly to a quadrantectomy and the final diagnosis revealed a dermatofibrosarcoma protuberans, 1. 8 cm in its greatest microscopic dimension, located 0.1 cm from the upper surgical margin. To ensure the wide resection margins required for this type of neoplasm, a re-excision was performed.ConclusionA dermatofibrosarcoma protuberans of the breast is an uncommon discovery. The aim of this case report is to highlight the importance of the surgical procedure in cases of the discovery of dermatofibrosarcoma protuberans. Re-excision may be necessary to ensure adequate resection margins.

A 3‐year old male entire Lhasa Apso presented with a swelling on the right ventral aspect of the mid‐cervical area. Mature connective tissue was identified on histopathologic examination of an incisional biopsy sample. Magnetic resonance imaging demonstrated a mass, possibly in three parts, characterized by striking hypointensity in T1‐weighted, T2‐weighted and T2* gradient‐echo sequences. The tumor was surgically excised, and a proliferation of mature fibroblasts embedded in collagenous matrix was confirmed histologically. Localization and histopathologic features of this proliferation were similar to human nuchal‐type fibroma. Six months after surgery, there was no evidence of recurrence and excision appeared curative.
