Article Abstract

Ovarian cystic follicles are the sign of important causes of reproductive failure in numerous species. In this review, some morphological, endocrinological and clinical aspects of cystic follicles in women, cows, mares, sows and bitches are discussed. Follicular cysts are the consequence of the failure of a mature follicle to ovulate at the appointed time of ovulation in the estrous cycle. Although the etiology of follicular cysts remains unknown, this review examines the evidence about the role of endocrine signaling systems in the specific disease or syndrome in each of the species mentioned above. This review also describes, the changes in the pathways of endocrine mechanisms that would trigger disturbances in the intraovarian component underlying the aberrant persistence of follicular cysts. The knowledge of the morphological and endocrinological nature of cystic follicles in different species can provide relevant information to better understand specific diseases when it is integrally analyzed from the comparative medicine viewpoint.

Tightly regulated cell-cell and cell-niche intercommunications via intertwined signaling networks are involved in maintaining normal hair follicle (HF) homeostasis, cycling and cell fate determination. However, knowledge of specific mechanisms by which hair loss takes place under pathological situations is needed. Using a keratinocyte-specific knockout mouse model, we uncover that the G-protein-coupled receptor kinase 2 (GRK2) signaling node plays a key role in HF homeostasis.

Background: Ulceroproliferative lesions involving the eyelids can be due to several causes, chief among them being squamous cell carcinoma (SCC). It is imperative to distinguish it from various mimics owing to the limited surgical therapy that can be offered at the site. Inverted follicular keratosis (IFK) is a rare benign epidermal tumor that arises from the infundibular portion of the hair follicle.

Background: Polycystic Ovary Syndrome (PCOS), is a complex endocrine disorder affecting 6-21% of reproductive-aged women, characterized by chronic anovulation, hyperandrogenism, and polycystic ovarian morphology. Current clinical management relies on lifestyle modifications and symptom-targeted therapies due to the absence of curative interventions. In recent years, Laparoscopic ovarian drilling (LOD), a surgical procedure that induces controlled ovarian damage to stimulate primordial follicle activation and regulate follicular growth, has emerged as an established therapeutic intervention for infertility in PCOS.

Acne conglobata is a severe, often eruptive, form of acne included in the follicular occlusion tetrad along with hidradenitis suppurativa, pilonidal cysts, and dissecting cellulitis of the scalp. The pathogenesis is complex and likely multifactorial with contribution from both extrinsic and intrinsic factors. Studies have shown a slight male predominance.
