INTRODUCTION Bizarre leiomyoma is a rare leiomyoma variant that requires a precise histopathological evaluation. Especially when diagnosed in a younger woman, this tumor leads to challenging treatment issues involving fertility preservation. Owing to the low incidence of bizarre leiomyoma, there is insufficient evidence to support myomectomy alone as an appropriate management option. Also, the ...

The cephalic neural crest (NC) of vertebrate embryos yields a variety of cell types belonging to the neuronal, glial, melanocytic and mesectodermal lineages. Using clonal cultures of quail migrating cephalic NC cells, we demonstrated that neurons and glial cells of the peripheral nervous system can originate from the same progenitors as cartilage, one of the mesectodermal derivatives of the NC....

Round ligament leiomyoma of uterus is rare. It can be presented as inguinal swelling mimicking the inguinal hernia or lymph node. Surgical excision is its curative treatment. Definitive diagnosis is made by histopathological examination. A 32 year old pregnant patient having round ligament leiomyoma as diagnosed histopathologically in Recep Tayyip Erdogan University Hospital in 2014 was present...

From a library of DNA fragments associated with Ultrabithorax protein in vivo, we have isolated nessy, a new Drosophila gene that encodes a putative transmembrane protein conserved in evolution from Caenorhabditis elegans, to human. Zygotic expression occurs transiently in mesectodermal cells at gastrulation, proceeds in mesoderm and endoderm lineages during germ band movements and becomes then...

Primary leiomyoma of the pleura is extremely rare. A 45-year-old man presented with a complaint of right chest pain. Chest computed tomography demonstrated a solid, round pleural mass in the right anterior chest wall. The mass was completely resected, and histopathological examination revealed a localized primary pleural leiomyoma. The patient was followed and has been disease-free for over 15 ...

Nasal leiomyoma, a benign tumor composed of smooth muscle cells, is rare in the head and neck region. Cellular leiomyomas of the uterus exhibit high intensity on T2-weighted images. Here we present a case of nasal leiomyoma in which the pathologic findings are similar to those of cellular leiomyoma. The present case exhibited slightly elevated intensity on T2-weighted images and marked enhancem...

This report shows for the first time clinical imaging (ultrasound and computed tomography), histological and immunohistochemical findings of an ovarian leiomyoma, coincidentally diagnosed in an asymptomatic unmated nulliparous ten year-old German shepherd bitch concurrently suffering from multiple mammary tumors. A thorough examination allowed the differentiation of ovarian leiomyoma from other...

We report the case of a calcified parasitic leiomyoma in a 51-year-old postmenopausal woman with lower abdominal discomfort. She had no history of surgery. Workup confirmed a calcified leiomyoma. On laparoscopy, the mass was separate from the uterus and adhered to the bowel and bladder. Histopathological examination confirmed a calcified leiomyoma. A calcified parasitic leiomyoma in a postmenop...

Leiomyoma is a smooth muscle tumor which rarely turns into malignancy. This is an unusual case report which presents leiomyoma on gingiva with osseous involvement. This case highlights the importance of histopathological examination for the proper diagnosis of any gingival growth. A 28-year-old female patient reported with localized gingival enlargement. The surgical excision was conducted and ...
