Nevus lipomatosus superficialis is a rare form of hamartoma or connective tissue nevus that is characterized by the presence of ectopic adipose tissue within the dermis. They usually present as soft yellowish or skin colored papulonodules with a predilection for the buttocks, upper thigh, and lumbar back. We report a solitary form of nevus lipomatosus superficialis in a 63-year-old woman who presented with a skin colored pedunculated mass. Histopathology showed mature adipocytes in lobules extending to the papillary dermis.

AbstractLipomas are common benign connective tissue tumours composed of adult adipose tissue. They are relatively rare in the upper aerodigestive tract, although they occur with considerable frequency in other areas, particularly in the subcutaneous tissues of the neck. Although there are several reports of this tumour occurring in the oropharynx, there is no recorded case of a lipoma of the tonsillar fossa. An 83-year-old man with a left tonsillar fossa lipoma is presented. Clinical presentation, management and a literature review are discussed.

Severity Of The Disease

The adipose tissue, apart from storing energy, plays a role of an endocrine organ. One of the most important adipokines secreted by adipose tissue is adiponectin, which is also produced by cardiomyocytes and connective tissue cells within the heart. Adiponectin is known for its beneficial effect on the metabolism and cardiovascular system and its low level is a factor of development of many cardiovascular diseases. Paradoxically, in the course of heart failure, adiponectin level gradually increases with the severity of the disease and higher adiponectin level is a factor of poor prognosis. As a result, there is a growing interest in adiponectin as a marker of heart failure progression and a predictor of prognosis in the course of this disease.

Introduction. Cystadenofibromas are tumors of the ovary which originate from the surface coelomic epithelium. Benign mucinous cystadenofibroma is a very rare form of these tumors, which consists of dominant stromal component of the connective tissue and one or more cysts. Case report. The case of a 62-year-old female with tumor of right ovary is reported in this paper. Histologically, tumor of the ovary had multilocular cystic formation, lined by a single-layer of mucoproductive cylindrical epithelium - endocervical type. In one area of tumor, the stromal component was abundant and made from partially hyalinised dense connective tissue. Mucinous cystadenofibroma was diagnosed on the basis of histological examination. Since the mucinous type of cystadenofibroma or adenofibroma is rare, this case has been chosen to be presented. Conclusion. Mucinous cystadenofibromas are differentially- diagnostically very similar to different malignant tumors and it is extremely important to make correct diagnosis of these neoplasms.

Ріст папілярного шару дерми шкі-ри телиць супроводжується внутрішніми струк-турними перетвореннями папілярного шару дерми. У ранньому віці чітко проявляються відмінності в архітектоніці колагенової сітки на субепідермаль-ному рівні папілярного шару дерми у різних порід телиць. Papillary dermis layer of skin of heifers has a complex heterogeneous organization of intercellular substance of connective tissue and topographically divided on morphological characteristics of collagen, elastic, reticular fibers and basic substance on several levels. Growth of papillary dermis of heifers’ skin is accompanied by internal structural transformations of papillary dermis. At an early age the differences in the architectonics of collagen network on subepidermal level of papillary dermis in various breeds of heifers are clearly seen.

Abstract The digital cushion is characterized as a modified subcutaneous tissue that absorbs the shock during gait, assists venous return of the hoof and supports a considerable part of body weight. Digital cushions have particular importance in the pathogenesis of the hoof, since they need to properly work in order to prevent compression and traumas in soft tissues. This study aimed to measure and determine how is the arrangement of these structures, and for this it was established the proportions of connective, adipose, vascular tissues and collagen fibers and collagen types found in palmar and plantar digital cushion of bovine using fore and hindlimbs of twelve adult zebu cattle of both sexes, 11 male and one female, with 269kg average carcass weight and without limb disorders. Fragments of cushions were subjected to conventional histology, cut to a thickness of 4µm and stained with Red Picrosirius. With digital optical microscope, the quantification of the connective tissue and differentiation of types of collagen used the Image Pro Plus® software, and of adipose and vascular tissue, the test point system. The mean and standard error were estimated with the GraphPad Prism 5.0 software, and then data were subjected to Kolmogorov-Smirnov normality test and Student's t-test with significance level set at 5% for determining the amount of different tissues between fore and hindlimbs of studied animals. In forelimbs the mean and standard error of the connective tissue proportion was 50.10%+1.54, of the adipose tissue was 21.34%+1.44, and of vascular tissue was 3.43%+0.28. Hindlimbs presented a proportion of connective tissue of 61.61%+1.47, 20.66%+1.53 of adipose tissue, and 3.06%+0.20 of vascular tissue. A significant difference (p<0.001) was detected in the connective tissue proportion between fore and hindlimbs. Types I and II collagen fibers have presented, respectively, a proportion of 31.89% and 3.9% in forelimbs and 34.05% and 1.78% in hindlimbs. According to the used methodology, digital cushions had a clear differentiation relative to adipose tissue between fore and hindlimbs.

Restrictive Dermopathy

Lethal restrictive dermopathy is genodermatoses associated with lamin protein defects resulting in connective tissue abnormalities of skin, musculoskeletal, and adipose tissue. We report one such case with a mutation in the ZMPSTE24 gene which is involved in lamin protein synthesis, resulting in fetal akinesia or hypokinesia deformation sequence. Early recognition in the perinatal period of distinctive clinical and skin histological features followed by molecular diagnosis enabled genetic counseling for the affected family.

Abstract: Thyrolipoma or thyroid adenolipoma is an extremely rare form of thyroid adenoma, which also contains mature adipose tissue and follicles covered with fibrous capsule. We present the case of the growing cervical lesion of a 52-year-old female with diabetes, which was removed during total thyreoidectomy. Autoimmune thyroiditis, bilateral papillary carcinoma and cervical thyrolipoma have been identified by the histopathological examination of the thyroid gland. Orv Hetil. 2018; 159(25): 1024–1032.

Abstract Background: Adipose tissue-derived microvascular fragments (MVF) represent effective vascularization units for tissue engineering. Most experimental studies in rodents exclusively use epididymal adipose tissue as a visceral fat source for MVF isolation. However, in future clinical practice, MVF may be rather isolated from liposuctioned subcutaneous fat tissue of patients. Therefore, we herein compared the vascularization characteristics of MVF isolates from visceral and subcutaneous fat tissue of murine origin. Methods: MVF isolates were generated from visceral and subcutaneous fat tissue of donor mice using two different enzymatic procedures. For in vivo analyses, the MVF isolates were seeded onto collagen-glycosaminoglycan scaffolds and implanted into full-thickness skin defects within dorsal skinfold chambers of recipient mice. Results: By means of the two isolation procedures, we isolated a higher number of MVF from visceral fat tissue when compared to subcutaneous fat tissue, while their length distribution, viability and cellular composition were comparable in both groups. Intravital fluorescence microscopy as well as histological and immunohistochemical analyses revealed a significantly reduced vascularization of implanted scaffolds seeded with subcutaneous MVF isolates when compared to implants seeded with visceral MVF isolates. Light and scanning electron microscopy showed that this was due to high amounts of undigested connective tissue within the subcutaneous MVF isolates, which clogged the scaffold pores and prevented the interconnection of individual MVF into new microvascular networks. Conclusion: These findings indicate the need for improved protocols to generate connective tissue-free MVF isolates from subcutaneous fat tissue for future translational studies.
