This case illustrates the rare association between hidradenitis suppurativa (HS) and Dowling-Degos disease (DDD). Furthermore the association of HS, DDD and multiple epidermal cysts has not to our knowledge been described before, but their coexistence in the same patient is likely to reflect the same follicular anomaly. It is possible that a single underlying defect of follicular proliferation ...

In the study, the gene expression of several heat shock proteins (HSPs) was determined in normal follicles and cystic follicles from cattle. A lower expression of HSP10 and HSP40 was observed in granulosa and theca cells of cysts compared to normal follicles. HSP27 was significantly less expressed in granulosa cells in cystic and large antral follicles than in other follicular categories. HSP60...

Ovarian follicular growth and development are regulated by extraovarian and intraovarian factors, which influence granulosa cell proliferation and differentiation. However, the molecular mechanisms that drive follicular growth are not completely understood. Ovarian follicular cysts are one of the most common causes of reproductive failure in dairy cattle. Nevertheless, the primary cause of cyst...

We herein describe a rare case of multilocular thymic cysts (MTCs) with follicular hyperplasia. The patient was a 50-year-old man, who was symptom-free. A mediastinal mass was found on chest computed tomography (CT) followed after pancreatitis. Chest CT revealed a 30 × 10 mm anterior mediastinal mass with multiple cystic lesions. Magnetic resonance imaging showed an anterior mediastinal cystic ...

A single injection of estradiol valerate induces a form of cystic ovary resembling some aspects of the human polycystic ovarian syndrome. Preceding the development of follicular cysts, there is an increase in intraovarian synthesis of nerve growth factor (NGF) and the low affinity NGF receptor (p75 NGFR). Selective blockade of NGF actions and p75 NGFR synthesis in the ovary restored estrous cyc...

BACKGROUND Female mice and rats injected with estrogen perinatally become anovulatory and develop follicular cysts. The current consensus is that this adverse response to estrogen involves the hypothalamus and occurs because of an estrogen-induced alteration in the GnRH delivery system. Whether or not this is true has yet to be firmly established. The present study examined an alternate possibi...

Pachyonychia congenital (PC) is a rare genodermatosis affecting the nails, skin, oral mucosae, larynx, hair, and teeth. General clinical presentation includes thickening of finger and toenails, painful plantar keratoderma, hyperhidrosis, oral leukokeratosis, follicular keratosis, palmar keratoderma, cutaneous cysts, hoarseness, twisted hair and prenatal or natal teeth. Clinically, PC is d...
