We report 2 ovarian sex cord-stromal tumors, a luteinized adult granulosa cell tumor and a cellular fibroma, with melanin pigment. These occurred in 44 and 61-yr-old patients, respectively. As far as we are aware, melanin pigment has not been described previously in an ovarian sex cord-stromal tumor, although it has been reported in a testicular Sertoli cell tumor. We review ovarian neoplasms containing melanin pigment.

Authors: Neagu TP, Ţigliş M, Popescu A, Enache V, Popescu ŞA, Lascăr I Abstract Ledderhose disease or plantar fibromatosis is a rare hyperproliferative disorder of the plantar aponeurosis, clinically characterized by nodules situated especially on the medial border of the foot. It is histopathologically associated with Dupuytren's disease. This disease has some risk factors, like old age, alcohol or nicotine abuse, liver dysfunction, trauma or exposure to vibrations and autoimmune disorders, but the exact etiology is still unknown. Even though it is benign, the local manifestations can be aggressive, leading to...

Management of desmoid tumors is challenging. In the current study, we report long-term outcomes of patients treated for desmoid fibromatosis using radiation therapy. We confirmed a high rate of relapse among young patients using a larger cohort than prior studies. We observed the greatest risk for patients ≤ 30 years of age independent of local treatment strategy. These data highlight the need for risk-adapted treatment decisions and confirm the need for patient management at expert multidisciplinary referral centers.

AbstractDesmoid tumours are known for their varied clinical behaviour. Hence, choosing an ideal treatment protocol remains challenging. This is further complicated by the rarity of these neoplasms and high recurrence rates following treatment. In our study, we tried to answer these questions in the background of Indian scenario. This is a retrospective study of 41 patients with extremity fibromatoses who were operated between June 2002 and November 2012. The mean age for all patients was 29.2  years with 30 females and 11 males. The mean duration of follow-up was 4.37 years. Eight patients were margin-positive on...

We describe the case of a 34-year-old woman who presented with a painful parotid mass. She was found to have an EAF of her right parotid gland. Medical management with antibiotics and immunosuppression therapy was unsuccessful. Surgical resection was required for both a definitive diagnosis and management. Preoperative findings on computed tomography, magnetic resonance imaging, and both fine-needle aspiration biopsy and surgical biopsy were nonspecific, as is typical in EAF cases.

CONCLUSIONS.—: The essay begins with remarks on the oftentimes straightforward stromal tumors of the ovary because the commonest of them, the fibroma, dominates from the viewpoint of case numbers. Then, the sclerosing stromal tumor and the peculiar so-called luteinized thecomas of the type associated with sclerosing peritonitis are discussed in greater detail and their wide spectrum is illustrated. Brief mention is made of 2 rare neoplasms: the ovarian myxoma and signet-ring stromal tumor. Discussion then turns to the more recently recognized intriguing tumor tentatively designated microcystic stromal tumor and the c...

AbstractChondromyxoid fibroma (CMF) is a rare benign bone neoplasm that typically occurs in young adults. Juxtacortical or surface-type CMF are rarer still and we present the case of a surface-type CMF in a 78-year-old woman, with only one other case described in a patient of a similar age previously. This patient was an otherwise healthy woman who presented for evaluation of a palpable lump in the anterior proximal tibia. Initial radiographs obtained demonstrated a focal soft tissue fullness immediately anterior to the anterior cortex of the proximal tibia, which contained faint chondroid-like matrix internally. There was...

CONCLUSION: The most common OBNs were fibroma, papilloma, fibroblastoma, lipoma and hemangioma. Overall, the OBN presented common clinical features; however, in particular cases, there are some characteristics that can lead the professionals to the correct diagnosis. Nevertheless, in general, histopathological analysis must be performed to confirm diagnosis. Intraosseous tumors and large lesions may require imaging tests to help diagnosis.
