BACKGROUND: Elevated MYB expression has been documented in adenoid cystic carcinoma (ACC), cylindroma, and spiradenoma, but the specificity of this finding is unknown. CD117 and SOX-10 expression also occurs in some cutaneous adnexal tumors. This study assesses MYB, CD117, and SOX-10 expression in cutaneous adnexal tumors. METHODS: Retrospective analysis of 184 benign adnexal tumors (140 eccrine/apocrine, 40 follicular, and 10 sebaceous), and 30 malignant adnexal tumors was performed with MYB, SOX-10, and CD117 immunostaining...

BACKGROUND: Neuroendocine carcinoma of the gynecologic tract is rare and poses a significant clinical challenge because of tumor heterogeneity and lack of standardized guidelines for treatment. Ovotestis refers to the histology of a gonad that contains both ovarian follicles and testicular tubular elements. Ovotesticular disorder of sexual development occurs in fewer than 10% of all disorders of sexual development. Gonadal tumors with malignant potential occur in 2.6% of all cases of ovotesticular disorder of sexual development...

REVIEW
Márcia Mendonça Carneiro, Rívia Mara Lamaita, Márcia Cristina França Ferreira, Agnaldo Lopes Silva-Filho
Almost 5% of women with endometrial cancer are under age 40, and they often have well-differentiated endometrioid estrogen-dependent tumors. Cancer survival rates have improved over the last decades so strategies to avoid or reduce the reproductive damage caused by oncologic treatment are needed. We reviewed the published literature to find evidence to answer the following questions: How should we manage women in reproductive age with endometrial cancer? How safe is fertility preservation in endometrial cancer? Can pregnancy influence endometrial cancer recurrence? What are the fertility sparing options available? Progestins may be prescribed after careful evaluation and counseling...

Oncocytes are epithelial cells characterized by their abundant eosinophilic and finely granular cytoplasm. Their histologic appearance is due to excessive amounts of cytoplasmic mitochondria. Oncocytes generally occur in the setting of benign neoplasms. Oncocytomas, or tumors composed primarily of oncocytes, are typically found in the kidneys. Other common sites include the salivary, thyroid, and parathyroid glands. Oncocytic metaplasia has only been rarely reported in various cutaneous neoplasms. We report a case of an elderly male presenting with a 5 millimeter erythematous papule on his left scalp, who underwent a shave biopsy showing a nodular, dermal-based adnexal tumor with prominent ductal differentiation, composed of multiple small, well-formed lumina surrounded by enlarged, bland-appearing epithelioid cells...

BACKGROUND: Ovarian tumour in children and adolescent girls form an uncommon but important part of gynaecological malignancies. They account for 1% of all the childhood malignancies and 8% of all abdominal tumours in children. Since the ovarian cysts are thought to arise from mature follicles, these tumours were considered to be infrequent in the paediatric population. AIM: The rarity of this condition prompted us to conduct this study and share our experience on the incidence and clinicopathological features of different ovarian tumours in girls up to 20 years of age observed in last 25 years at a single tertiary care hospital...

BACKGROUND: The incidence of rare cutaneous malignancies is unknown. Current estimates of rare cutaneous malignancy incidences are based on broad epidemiologic data or single institution experiences, not population-based data. OBJECTIVE: To determine the incidence of several rare nonmelanoma skin cancers. MATERIALS AND METHODS: The authors conducted a retrospective chart review of a population-based cohort between the years 2000 and 2010. Residents of Olmsted County, Minnesota, who were diagnosed with a biopsy-proven nonmelanoma skin cancer-excluding basal cell carcinoma and squamous cell carcinoma-were included in this study...

BACKGROUND: Vitreoretinal lymphoma (VRL), the most common lymphoma of the eye, is a rare form of primary CNS lymphoma (PCNSL). Most frequently a high-grade diffuse large B cell lymphoma, VRL can cause vision loss and its prognosis remains dismal: the overall survival time is 3 years after diagnosis. Radiotherapy and chemotherapy are used but remain frequently ineffective, and no standardized treatment regimen exists. Furthermore, no biologically targeted treatments, based on the genetic profile of the tumor, are available, as VRL has hitherto not comprehensively been profiled...

Distinguishing primary cutaneous adnexal carcinoma from metastatic carcinoma of unknown primary can be a diagnostic challenge due to the frequent overlap of histologic and immunohistochemical features. A 58-year-old man presented with a tender, indurated plaque on axillary skin. Biopsy revealed infiltrating atypical cells throughout the dermis, without connection to the epidermis. Tumor cells had a histiocytoid appearance and displayed mild pleomorphism. The tumor was discohesive and had areas with a single file pattern...

Mature cystic teratoma of ovary is a common benign adnexal tumor in females. Malignant transformation in a mature cystic teratoma of the ovary occurs in only 1 - 2% of cases. Most common malignant transformation is squamous cell carcinoma (70-80% of cases), occurring mostly in postmenopausal women with large sized cysts. Here, we report a case of 46-year lady who presented with pain in lower abdomen. Ultrasound and CT scan revealed complex adnexal mass measuring 16x9 cm. Size and older age of the patients should be regarded as important predictors of malignant transformation in mature cystic teratoma...

Paraovarian cysts are a rare pathology, constituting 10-20% of the adnexal masses. The origin can be represented by paramesonephric ducts (Hydatid cysts of Morgagni), vestiges of mesonephric ducts also represented by mesothelium, or neoplastic (cystadenomas or cystadenofibromas) that are mostly benign. Borderline or malignant paraovarian tumors are encountered less often. This article presents a case of paraovarian cyst in a 37-year-old patient, with a history of 2 pregnancies, completed by cesarean. The patient sought medical attention for an asymptomatic voluminous ovarian cyst, detected in a routine ultrasound scan...

Trichogerminomas are rare adnexal neoplasms first described by Sau et al in 1992. Including the initial report, 20 cases have been reported, all with similar histological features, namely tumor nodules composed of basaloid cells that form densely packed, round nests or "cell balls" and which demonstrate variable degrees of pilosebaceous differentiation. In this study, the authors report a case of a trichogerminoma with pilomatrical differentiation and a unique immunohistochemical profile. The patient is a 71-year-old man with a well-delineated nodule on the top of the scalp...

Frederik Holm Svendsen, Steffen Heegaard
Lymphoma of the eyelid constitutes 5% of ocular adnexal lymphoma. In previously published cases, 56% of lymphomas of the eyelid are of B-cell origin and 44% are of T-cell origin. The most frequent B-cell lymphomas are extranodal marginal zone lymphoma (27 cases-14%) and diffuse large B-cell lymphoma (18 cases-9%). T-cell lymphomas are most frequently mycosis fungoides (25 cases-13%), extranodal natural killer/T-cell, nasal-type lymphoma (12 cases-6%), and primary cutaneous anaplastic large-cell lymphoma (12 cases-6%)...

PURPOSE: Chromosomal instability is a hallmark of ovarian cancer. Here, we explore copy number alteration (CNA) profiling in cell-free DNA as a potential biomarker to detect malignancy in patients presenting with an adnexal mass. EXPERIMENTAL DESIGN: We prospectively enrolled 68 patients with an adnexal mass, of which 57 were diagnosed with invasive or borderline carcinoma and 11 with benign disease. Cell-free DNA was extracted from plasma and analyzed by low-coverage whole-genome sequencing...
