Paraneoplastic pemphigus (PNP) is an autoimmune disorder stemming from an underlying tumor. It is hypothesized that antigens associated with the tumor trigger an immune response resulting in blistering of the skin and mucous membranes .
In mild disease, patients present with eyelid retraction. In fact, upper eyelid retraction is the most common ocular sign of Graves' orbitopathy. This finding is associated with lid lag on infraduction (Von Graefe's sign), eye globe lag on supraduction (Kocher's sign), a widened palpebral fissure during fixation (Dalrymple's sign) and an incapacity of closing the eyelids completely ...
Hailey–Hailey disease (HHD), or familial benign chronic pemphigus [1]: 559 or familial benign pemphigus, [2]: 622 was originally described by the Hailey brothers (Hugh Edward and William Howard) in 1939. [3] [4] It is a genetic disorder that causes blisters to form on the skin.
There are many diseases known to cause ocular or visual changes. Diabetes , for example, is the leading cause of new cases of blindness in those aged 20–74, with ocular manifestations such as diabetic retinopathy and macular edema affecting up to 80% of those who have had the disease for 15 years or more.
Other risk factors include radiation, smoking, HPV, arsenic, and exposure to polycyclic hydrocarbons. [1] Conjunctival SCC is often asymptomatic at first, but it can present with the presence of a growth, red eye, pain, itching, burning, tearing, sensitivity to light, double vision, and decreased vision.

Thyroid-associated ophthalmopathy (TAO), or thyroid eye disease (TED), is the most common extrathyroidal manifestation of Graves' disease. It is a form of idiopathic lymphocytic orbital inflammation , and although its pathogenesis is not completely understood, autoimmune activation of orbital fibroblasts , which in TAO express the TSH receptor ...
Pemphigus is further divided in two major subtypes: pemphigus vulgaris (PV) and pemphigus foliaceus (PF). However, several other disorders such as IgA pemphigus, IgE pemphigus, pemphigus herpetiformis, drug-induced pemphigus, Senear Usher syndrome, and endemic pemphigus foliaceus exist, and are recognized by a dermatologist from the appearance ...
Pemphigus foliaceus is an autoimmune blistering disease of the skin. [1] Pemphigus foliaceus causes a characteristic inflammatory attack at the subcorneal layer of epidermis, which results in skin lesions that are scaly or crusted erosions with an erythematous (red) base. [2] Mucosal involvement is absent even with widespread disease. [3]
