The aim of the study was to determine the accuracy of a frozen section and the factors affecting the accuracy of frozen diagnosis of ovarian neoplasms. This retrospective, cross-sectional study was conducted on 401 patients with ovarian masses with frozen section diagnosis in Shahid Faghihi Hospital affiliated to Shiraz University of Medical Sciences between 2014 and 2018.

Physicochemical, Mineralogical, and Mechanical Properties of Calcium Aluminate Cement Concrete Exposed to Elevated Temperatures.

One commonly used cement type for thermal applications is CAC containing 38-40% alumina, although the postheated behavior of this cement subjected to elevated temperature has not been studied yet. Here, through extensive experimentation, the postheated mineralogical and physicochemical features of calcium aluminate cement concrete (CACC) were examined via DTA/TGA, X-ray diffraction (XRD), and scanning electron microscopy (SEM) imaging and the variation in the concrete physical features and the compressive strength deterioration with temperature rise were examined through ultrasonic pulse velocity (UPV) values. In addition, other mechanical features that were addressed were the residual tensile strength and elastic modulus.

Value of CD123 Immunohistochemistry and Elastic Staining in Differentiating Discoid Lupus Erythematosus from Lichen Planopilaris.

Background: Differentiating scarring alopecia secondary to lichen planopilaris (LPP) and discoid lupus erythematosus (DLE) has always been a challenge clinically and pathologically. Plasmacytoid dendritic cells (PDCs) have been reported in the cutaneous lupus erythematosus by CD123 immunostaining. This study assesses CD123 marker positivity and patterns of elastic fiber loss in scalp biopsy to differentiate DLE from LLP.

Comparison of Serum Level of Sex Hormones in Patients with Frontal Fibrosing Alopecia with Control Group.

Context: Although etiopathogenesis of frontal fibrosing alopecia (FFA) is not fully discovered, it seems that hormonal factors play a role.

Settings And Design: This was a case-control study.

Cutaneous lymphoid hyperplasia induced by Hirudo medicinalis (leeches).

For centuries, Hirudo medicinalis (medicinal leech) has been used as a remedy to treat many discomforts, such as muscle and joint pain. Nowadays, using leech in reconstructive surgery, microsurgery, wound and flap healing, venous insufficiency, varicosities and many other disorders has increased. In this study, we report a 45 year old female patient with six pruritic papules on her legs since10 months ago that appeared about 4 weeks after one session of leech application.

Fallopian Tube Epithelial Changes in Ovarian Serous Tumors Compared with Control Group: A Single-Center Study.

Background: Recent studies have hypothesized that distal end of fallopian tube is a possible origin of ovarian serous carcinoma. This study investigated histopathological changes in fallopian tube epithelium (FTE) of the patients with ovarian serous tumors compared with control group.

Materials And Methods: In a prospective cross-sectional study, fallopian tubes (right and left) of 34 cases with ovarian serous tumors were collected from patients who underwent surgery in two major gynecological centers affiliated to Shiraz University of Medical Sciences, Shiraz, Iran (2012-2015).

Hypo-pigmented mycosis fungoides is a rare malignancy in pediatrics.

Hypopigmented mycosis fungoides (HMF) is an uncommon form of cutaneous T-cell lymphoma. It can be seen in children and is usually mistaken for eczema, vitiligo, or progressive macular hypomelanosis, clinically and histopathologically. We present a boy with HMF confirmed by histopathology.

Primary intrauterine dysgerminoma in a pregnant woman: A rare case report.

Primary extraovarian dysgerminoma is very rare. Nearly all reported uterine germ cell tumors are nondysgerminoma. Herein, we reported a primary intrauterine dysgerminoma.

Crusted scabies masquerading as psoriasis plaques in a patient suffering from burn scars.

A 30-year-old woman, presented with erythematous scaling plaques on her trunk with severe pruritus and a burning sensation that began 3 months prior to her visit. She had a history of a thermal burn in that area, three years prior. Topical corticosteroid application for 3 months had no positive effects.

Satisfactory treatment of a large connective tissue nevus with intralesional steroid injection.

Collagenoma is a type of connective tissue nevi, a rare hamartomatous malformation characterized by the predominant proliferation of normal collagen fibers and normal, decreased, or increased elastic fibers. Collagenomas present as multiple or solitary, hereditary or sporadic, asymptomatic, skin-colored papules, nodules, and plaques with variable sizes, and are usually located on the trunk, arm, and back. Here, we report on a 14-year-old boy who presented with an isolated giant collagenoma of the frontal area that dramatically responded to intralesional triamcinolone acetonide.

Autoimmune progesterone dermatitis presenting as fixed drug eruption: a case report.

Autoimmune progesterone dermatitis (APD) is a rare disorder characterized by periodic skin lesions that erupt during the luteal phase of the menstrual cycle. Clinical manifestations of APD is caused by an unusual allergy to progesterone and has a wide range of clinical manifestations from eczema and urticaria to angioedema and erythema multiforme. A 46-year-old woman described recurrent, round erythematous plaques on the lower lip, both forearms and buttocks.

Infantile multiple large pyogenic granuloma on burned skin. Case report and review of literature.

Pyogenic granuloma (PG) is a benign vascular lesion of the skin and mucous membranes, presenting as a solitary, red, pedunculated papule that bleeds easily and which appears to be a reactive vascular proliferation to minor injury. These lesions are more common in children and are mostly seen in exposed sites. Multiple disseminated PG is a rare condition.
