Abstract Nodular hidradenoma is an uncommon cutaneous adnexal tumor arising from sweat glands. In the skin, it usually presents as a solitary dermal nodule; excision is curative in most cases. In rare instances, it may present as a breast mass and can mimic breast carcinoma clinically and radiologically, causing diagnostic dilemmas for the treating physician and pathologist. Herein, we discuss a case of nodular hidradenoma in a 20-year-old Hispanic woman as a rapidly growing mass in the breast that mimicked breast carcinoma. We discuss the rare presentation of this uncommon tumor and the differential diagnosis of this entity, as well as the results of our literature review on the topic.

Nodular Hidradenoma

Nodular hidradenoma (NH) is a benign adnexal tumor that arises from either eccrine or apocrine sweat glands. NH can originate from any cutaneous site, but the most common sites are the head and anterior surface of the trunk, with very rare cases in the extremities. Long-standing NH has been reported to undergo malignant transformation to malignant NH (MNH); however, its occurrence in the lower leg is extremely rare with only one other case reported to date. In this report, we present a rare case of MNH occurring in the lower leg which was resected with the intent to make a diagnosis. At the final follow-up after 11 months, no local recurrence or metastasis has been observed.

Syringocystadenoma papilliferum is a very rare, benign adnexal tumor that originates from the apocrine sweat glands. Herein, we report a 25-year-old male who presented with a 10-year history of an asymptomatic slowly growing skin lesion on his face. Skin examination revealed a solitary rounded 3 × 3 cm erythematous plaque with central crustation on the right side of his face. Punch skin biopsy was taken from the lesion. The epidermis showed downward papillomatous extensions. The dermis showed multiple epithelial sheets and dilated ducts that were lined by columnar cells. On the basis of the above clinicopathological findings, the diagnosis of syringocystadenoma papilliferum was made. The patient was reassured and referred to a surgeon for surgical excision of the lesion.

Diagnosis of metabolic storage disease can be established by the determination of enzymes or storage material in blood, urine, or several tissues or by clinical parameters. Identification of the accumulated storage products is possible by biochemical analysis of isolated material, by histochemical demonstration in sections, or by ultrastructural demonstration of typical inclusion bodies. In order to determine the significance of such inclusions in human skin biopsies several types of metabolic storage disease were investigated. The following results were obtained.In MPS type I (Pfaundler-Hurler-Syndrome), type II (Hunter-Syndrome), and type V (Ullrich-Scheie-Syndrome) mainly “empty” vacuoles were found in skin fibroblasts, in Schwann cells, keratinocytes and macrophages (Dorfmann and Matalon 1972). In addition, prominent vacuolisation was found in eccrine sweat glands. The storage material could be preserved in part by fixation with cetylpyridiniumchloride and was also present within fibroblasts grown in tissue culture.

The prevalence of strands shown by freeze-fracture in the zonula occludens of junctional complexes is thought to correspond closely with the transepi-thelial electrical resistance and with the tightness of the junction and its obstruction to paracellular flow.1 The complexity of the network of junc¬tional complex strands does not appear invariably related to the degree of tightness of the junction, however, as rabbit ileal junctions have a complex network of strands and are permeable to lanthanum. In human eccrine sweat glands the extent of paracellular relative to transcellular flow remains unknown, both for secretion of the isotonic precursor fluid by the coil and for resorption of a hypertonic solution by the duct. The studies reported here undertook, therefore, to determine with the freeze-fracture technique the complexity of the network of ridges in the junctional complexes between cells in the secretory coil and the sweat ducts. Glands from a patient with cystic fibrosis were also examined because an alteration in junctional strands could underlie the decreased Na+ resorption by sweat ducts in this disease. Freeze-fracture replicas were prepared by standard procedures on isolated coil and duct segments of human sweat glands. Junctional complexes between clear cells, between dark cells and between clear and dark cells on the main lumen, and between clear cells on intercellular canaliculi of the coil con¬tained abundant anastomosing closely spaced strands averaging 6.4 + 0.7 (mean + SE) and 9.0 +0.5 (Fig. 1) per complex, respectively. Thus, the junctions in the intercellular canaliculi of the coil appeared comparable in complexity to those of tight epithlia. Occasional junctions exhibited, in addition, 2 to 5 widely spaced anastomosing strands in a very close network basal to the compact network. The fewer junctional complexes observed thus far between the superficial duct cells consisted on the average of 6 strands arranged in a close network and 1 to 4 underlying strands that lay widely separated from one another (Fig. 2). The duct epitelium would, thus, be judged slightly more "leaky" than the coil. Infrequent junctional complexes observed to date in the secretory coil segment of a cystic fibrosis specimen disclosed rela¬tively few closely crowded strands.

The integumentary system covers the surface of the embryo (skin) and its specialized skin structures including hair, nails, sweat glands, mammary glands and teeth. During fetal skin development, the epidermis changes from a single layer of ectodermal cells at 7–8 days of gestation into a more apparent stratified, keratinized epithelium at 22–24 weeks. The aim of the study is to identify the histological and cytological changes that take place during neonatal and adult epidermis development. Human neonatal and adult samples were obtained from fully informed, consenting parent or releatives from Al-hilla mortary / Iraq. Neonatal samples were obtained from neonates after sudden deaths from maternity wards. Anatomical Sites included abdomen, forehead, back, shoulder and feet sole. A totoal of 15 neonates and 10 mature adults were used for this study. Fresh tissues were sectioned using a freezing cryostat. Tissues were sectioned at 5µm in -24°C and collected on microscopic slides. Slides were allowed to air dry for 30 min prior to hematoxyline and eosin staining. Tissues were also photographed using scanning electron microscopy SEM. Cytological measurements were taken using image j software and data was analysed using graph prism. Various cytological and histological changes takes place during neonatal and adult and epidermis development. Our study shows the stages of fair follicule formation as well as number of nucleated layers present at each stage of development and at different anatomical sites. Major histological changes takes places during the transition frm a neonate to a mature adult including the number of basal cells and epidermal thickness depending on the anatomical site.

Hereditary Condition

The personality of an individual is often judged by his looks. A beautiful smile brings immense pleasure, not only to the viewer but also to the wearer of the smile. Time and again in dentistry, esthetics has been the prime area of focus. Prosthodontic rehabilitation also involves esthetics as its key factor, which is challenging especially in patients with congenital diseases or syndromes. Ectodermal dysplasia is one such hereditary condition associated with failure of the development of ectoderm in the embryonic stage and can cause multiple abnormalities. The ectodermal structures like skin, nails, hair, sweat glands, and teeth are particularly affected. The management of ectodermal dysplasia is quite complex and multidisciplinary owing to the abnormal morphology in craniofacial structures, a wide array of dentofacial defects, and age of the affected individuals, as most of them are very young when they report for or are evaluated for treatment. The deciduous as well as the permanent dentition in these patients may present with anodontia, hypodontia or oligodontia or combination of these. Hypodontia is one of the most common intraoral finding among these scenarios. Therefore, the affected patients obviously require absolute attention towards prosthodontic treatments throughout their developmental years till their adulthood. This report presents a case of an adult diagnosed with having ectodermal dysplasia with hypodontia. By appropriate modification and customization, the prosthodontic management was meticulously planned for the young patient which involved a full mouth rehabilitation with tooth supported fixed prosthesis in the maxillary and mandibular arch. The devised treatment plan had a key impact on the psychological, the masticatory function, speech and facial esthetics of the patient.
