BACKGROUND: We present herein a series of 14 lesions showing overlapping features with the newly defined benign cutaneous mesenchymal neoplasm labelled as fibroblastic connective tissue nevus (FCTN). METHODS AND RESULTS: Eight patients were male and five were female, ranging in age from 1 to 56 years. Lesions appeared as isolated nodules or plaques on the trunk (7 cases), the limbs (4 cases) and the neck (2 cases). Histologically, all cases were composed of bundles of bland spindle cells of fibroblastic/myofibroblastic lineage irregularly branching within the reticular dermis and along fibrous septa in the subcutis...

PURPOSE: CD44 expression in both the early and metastatic phases of many epithelial and non-epithelial cancers is strongly prognostic. The objective of the study is to evaluate whether there is any relationship between the expression of CDD44v6 and endometrial cancer (EC) staging and prognosis. METHODS: This retrospective study included 60 EC patients for whom surgical staging was performed between 2000 and 2006. Twenty-eight randomly selected patients with normal endometria served as the control group...

OBJECTIVES: Elevated concentrations of polyamines have been found in urine of patients with malignant tumors, including ovarian cancer. Previous research has suffered from poorly standardized detection methods. Our liquid chromatography-tandem mass spectrometry (LC-MS/MS) method is capable of simultaneous standardized analysis of most known polyamines. Liquid chromatography-tandem mass spectrometry has not previously been used in the differential diagnostics of ovarian tumors in postmenopausal women...

Syringoid eccrine carcinoma is a rare malignant adnexal tumor that typically presents in the head and neck region. Involvement of the extremities is uncommon, with only a few cases reported in the literature. Here, we report our experience with a rare case of syringoid eccrine carcinoma occurring on the plantar surface of the right foot in a 47-year-old African American woman. Histologically, incisional biopsy revealed a tumor consisting of tubulocystic structures lined by basaloid cells with an infiltrative growth pattern, extending from the reticular dermis to the deep biopsy margin...

Primary mucinous eccrine carcinoma is a rare malignant adnexal tumor of older patients. The histopathological features of this tumor are well-established but the cytomorphology of this neoplasm has only been documented in a few cases. The cytology and histology of this tumor may mimic metastatic mucinous carcinoma and may cause a diagnostic dilemma, especially when the tumor is located at axilla. A correct diagnosis is important because the prognosis is better than that of a metastatic mucinous carcinoma. Here we report the cytological and histological features of a case of primary cutaneous mucinous carcinoma of axilla in an elderly male patient...

Basaloid follicular hamartoma (BFH) is a rare benign adnexal tumor with variable clinical presentation. We report a case of a 64-year-old man, who presented with an incidental finding of a 3mm hyperpigmented macule on his cheek. Dermoscopy revealed a structureless blue lesion. Histopathology examination showed interconnecting lobules and cords of bland pigmented epithelial cells within the dermal stroma, with the presence of pseudohorncysts. The lesional cells were faintly positive for Bcl2on immunohistochemical staining...

In view of the small number of recurrent and metastatic cases of female adnexal tumors of probable Wolffian origin (FATWO), there is a distinct lack of evidence to support recommendations regarding treatment. In the present study, a 37-year-old female was diagnosed with a left adnexal tumor and underwent a left salpingo-oophorectomy (SO). The tumor was found to arise from the left tubal fimbria and extend to the posterior leaf of the broad ligament. Pathological examination identified a number of solid, tubular and cystic architectures, with areas of hyalinization, hemorrhage and necrosis...

Autoamputated ovary with mature cystic teratoma (MCT) is a rarely reported gynecologic entity with an unknown prevalence. A 34-year-old woman referred to our clinic for presumed left ovarian tumor. Pelvic examination, ultrasonography and computed tomography scan revealed a 5-cm, cystic ovarian mass with calcification and fat component, and tumor markers were as follows, cancer antigen (CA) 125; 10.4 U/mL, CA19-9; 2 U/mL. Laparoscopy was performed. The mass was identified in the left adnexal region without any ligamentous or direct connection with the pelvic organs...

Polarizable calcium oxalate (CaOx) crystals have been well documented in breast biopsies, generally associated with benign apocrine metaplasia. In contrast, polarizable crystals are only rarely reported in skin adnexal neoplasms. We report three different cases of sweat gland tumors with polarizable crystals morphologically suggestive of CaOx: 1 apocrine hidrocystoma and 2 tubular apocrine adenomas. The histologic features were examined in 3 cases. Clinical presentation summary included 2 males and 1 female, ages 53 to 74, with lesions located on the left cheek, inferior vertex scalp and the left eyebrow...

The authors report and discuss a rare case of a gastrointestinal stromal tumor (GIST) in a 35-year-old female, which was pre-procedurally characterized as a right ovarian mass by magnetic resonance imaging (MRI) features. This manuscript reviews the imaging and clinical features of GISTs with pathologic correlation, and emphasizes how this entity may present a diagnostic challenge in certain anatomic regions owing in large part to its exophytic nature. This case is unique among similarly reported cases in that there was a "claw sign" with the right ovary, which provided convincing evidence of its point of origin...

Blitz nevi/tumors are a distinct subset of melanocytic neoplasia which show mixed morphologic features of Spitz and blue nevus. Genomically, most blue nevi have GNAQ or GNA11 mutations while most Spitzoid neoplasms have either an HRAS mutation or translocations involving MET, ROS, BRAF, ALK1, NTRK1, and RET. The criteria used for the assessment of malignancy in blue and Spitzoid lesions are different, and these lesions have different prognostic markers. In this study, we assess the clinical, morphological, and genomic changes in 18 cases of Blitz nevi/tumors to better characterize this subset of neoplasms and determine their optimal genomic classification...

OBJECTIVES: Primary ovarian fibrosarcomas are extremely rare neoplasms, and only 50 cases have been reported in the English literature. Diagnosis can be difficult because of this condition's rarity, and other similar appearing mesenchymal lesions should be ruled out. METHODS: A 50-year-old postmenopausal woman came to our hospital because of abdominopelvic pain. Ultrasonography revealed a 41x33 mm heterogeneous solid mass in the right ovary. Total blood counts, biochemical parameters, and tumor markers were within normal ranges...
