    Pathergy phenomenon

    Pathergy phenomenon is most commonly described in pyoderma gangrenosum and Behcet's disease, and is also noted in some cases of sweet's syndrome and subcorneal pustular dermatosis. Heavy neutrophlic infiltrates or pustular reaction that develop at the site of non-specific trauma are termed as pathergy phenomenon. Pathergy phenomenon is tested by the pathergy test, and it refers to the development of a new lesion at the site of eliciting the test. An erythematous papule of more than 2 mm at the prick site with a 20-22-gauge needle (to avascular skin obliquely to the depth of 5 mm following an intradermal injection of 0.1 ml of normal saline) is called as a positive pathergy test. Positive pathergy is regarded as one of the minor criteria for the diagnosis of Behcet's disease by the International Study Group Diagnostic criteria for Behcet's disease.

    Meirowsky phenomenon

    Meirowsky in 1909 discovered that pieces of fresh human skin showed irreversible darkening of the epidermal melanin if heated. This type of heat darkening came to be known as the
    Meirowsky phenomenon. Meirowsky phenomenon is among the first responses of human skin to ultraviolet (UV) exposure. It is also called as immediate pigment darkening (IPD). IPD is more pronounced within a few hours of sun exposure, and is due to metabolic changes coupled with the redistribution of melanin already present in the skin. The phenomenon is seen after exposure to long-wave UVB, UVA and, to some extent, visible radiation. IPD is not photo protective as it does not lead to a hardening effect as seen in delayed tanning

    Mauserung phenomenon

    In 1937, Siemens reported a family with features similar to, but distinct from, bullous congenital ichthyosiform erythroderma of Brocq (BCIE). This variant has been termed ichthyosis bullosa of Siemens (IBS), and has been reported to be distinguished clinically from BCIE by the absence of erythroderma, localization of dark grey hyperkeratosis to the flexural sites and areas of peeling of the skin among hyperkeratotic areas known as the "mauserung" phenomenon.

    A distinctive characteristic of IBS, which is not present in the other forms of ichthyosis, is called the "mauserung" phenomenon (mauserung is German for "moulting"). These are small patches of bare, apparently normal skin (due to regeneration of the epidermis) in the middle of areas of hyperkeratosis

    The manta ray sign is a radiographic appearance in bladder exstrophy. It describes wide midline separation of the pubic bones simulating the appearance of a manta ray swimming towards you 1. The smooth arc of the pelvis outline in bladder exstrophy is in contrast to acquired separation of the pubic symphysis seen in open book pelvic injuries.

    Fishtail deformity of the elbow is characterised by a contour abnormality of the distal humerus, which develops when the lateral trochlear ossification centres fails to develop or resorbs.
    It is an uncommon complication usually following a distal humeral fracture in childhood. Whilst initially presumed to be a benign condition, long-term follow-up suggests that patients with fishtail deformity are prone to:
    functional impairment
    ongoing pain and
    the development of early osteoarthrosis.
