Follicular bronchiolitis (FB) also known as hyperplasia of the bronchial associated lymphoid tissue (BALT), or bronchiolar nodular lymphoid hyperplasia, is an entity characterized by the development of lymphoid follicles with germinal centers in the walls of small airways. FB is thought to be caused by antigenic stimulation of BALT, followed by a polyclonal lymphoid hyperplasia. ⋯ FB is a pathological diagnosis that can be seen in several clinical settings, including connective tissue diseases, immunodeficiency states, autoimmune diseases, infections, obstructive airway diseases, as well as several types of interstitial lung diseases (ILDs). Its characteristics need to be carefully identified and differentiated from other closely related diseases in the group of LPDs due to significant differences in treatment and prognosis.

Telogen effluvium was first described by Kligman in 1961. It is a most common cause of diffuse hair loss. Women with telogen effluvium more frequently present to dermatologist. ⋯ Diffuse shedding of telogen hair are seen after 3-4 months of triggering event. The observation of increased telogen hair shedding does not infer a cause. Establishing aetiology of telogen effluvium requires elicitation of relevant history and appropriate laboratory investigations to exclude endocrine, nutritional and autoimmune disorders.
