To the best of our knowledge, this is the first report of MDM2 FISH amplification in a liposarcoma performed on an aspirate smear. [ncbi.nlm.nih.gov]

The patient underwent splenectomy, and the adipose tissue surrounding the splenic hilum was also resected. Microscopically, the tumor mainly consisted of high-grade spindle cells similar to those seen in undifferentiated pleomorphic liposarcoma. [ncbi.nlm.nih.gov]

In this case, we inferred that the hard nodule located beneath the previous incision was local recurrence; the suprapubic and inguinal masses were metastatic tumors either from the left intrascrotal tumor 2 years ago or from the right paratesticular DDL [ajandrology.com]

We present a case of a dedifferentiated liposarcoma arising in the soft tissue of the posterior neck of an 86-year-old man and diagnosed by fine-needle aspiration. Aspirate smears showed a dual population of atypical lipomatous and spindled cells. [ncbi.nlm.nih.gov]

Fine needle aspiration biopsy diagnosis of dedifferentiated liposarcoma: Cytomorphology and MDM2 amplification by FISH. [cytojournal.com]

The NDDLS-1 cell line was established from a pleural effusion associated with a lung metastasis. Pleomorphic tumor cells arranged in a haphazard growth pattern were seen in xenograft tumors. [ncbi.nlm.nih.gov]

The patient denied dysphagia or bucking (choking cough). The other physical examination findings were fairly unremarkable. [ajnr.org]

The use of MDM2 immunostaining in differentiating benign lipomatous tumours from well-differentiated liposarcomas is mentioned, which is of value especially in lipomatous tumours of the gut where ulcerated benign tumours can show varying degrees of atypia [ncbi.nlm.nih.gov]

Gross examination revealed a submucosal polyp without a mucosal ulcer. [wjgnet.com]

A contrast-enhanced CT scan of the head and neck revealed a large neck mass that had 3 components of differing attenuation, including a lipomatous region with thick septa, a low-attenuation high-water-content component, and a sporadic heterogeneous high-attenuation [ajnr.org]

The patient presented with a painless right scrotal mass. Magnetic resonance imaging showed a large mass along the right spermatic cord. [ncbi.nlm.nih.gov]

A woman who complained of dyspnea showed on imaging features a bulky posterior mediastinal mass which was completely excised and initially misdiagnosed as an angiomyolipoma. [ncbi.nlm.nih.gov]

We found an undiagnosed anterior mediastinal mass in a 56- year-old man for whom we performed a complete tumor resection through median sternotomy. [ncbi.nlm.nih.gov]

A woman who complained of dyspnea showed on imaging features a bulky posterior mediastinal mass which was completely excised and initially misdiagnosed as an angiomyolipoma. [ncbi.nlm.nih.gov]

The differential diagnosis of the pleural mass included malignant solitary fibrous tumor. Cytogenetic analysis showed supernumerary ring chromosomes in the pleural tumor, as well as strong amplification of MDM2 and CDK4 genes in both tumors. [ncbi.nlm.nih.gov]

The results favor a reactive lymphocytic infiltration versus a neoplastic one, which might be caused for example by chemoattractive agents. [ncbi.nlm.nih.gov]

The NDDLS-1 cell line was established from a pleural effusion associated with a lung metastasis. Pleomorphic tumor cells arranged in a haphazard growth pattern were seen in xenograft tumors. [ncbi.nlm.nih.gov]
