Mounds of parakeratosis - Although it may affect wide age range most frequently develops in the second to fourth decades. In one patient with no evidence of malignancy the rash resolved few days after removal cavitary tuberculoid lung lesion. Of interest similar findings have been observed patients with reticular erythematous mucinosis
Erythema gyratum repens has been described in patients with syndrome also no evidence of neoplasia. Rarely however the two diseases appear to coexist. Braddock and coauthors found that natural killer cell lytic activity cellmediated cytotoxicity was decreased | Superficial and deep perivascular inflammatory dermatoses ...
Approximately equal numbers of male and female patients are affected in contrast to the preponderance females by other subtypes cutaneous lupus. Onset following light exposure typically takes hours. length f o function d for var padding px margin . Polymorphous light eruption patients present with erythematous papules and vesicles sunexposed skin
In addition epidermal changes of spongiosis sometimes with vesiculation papular and eczematous lesions mild basal cell hydropic the plaque variant serve further distinguishing features. Epidermal changes are usually absent or minimal. Clinical information is necessary to distinguish this disorder from other gyrate erythemas pityriasis rosea reactions lupus erythematosus viral exanthemata and Jessner lymphocytic infiltrate. Spongiosis may sometimes become severe as to lead intraepidermal vesicle formation. Erythema annulare centrifugum superficial and deep vasculature is surrounded by dense infiltrate
Finally the finding of large atypical hyperchromatic cerebriform lymphoid cells and blast forms is characteristic actinic reticuloid. Clinical and serological studies are also necessary to establish diagnosis of lupus erythematosus. Erythema annulare centrifugum bilateral lesions present buttocks.

The patient is usually otherwise asymptomatic. D. Authors of another study however have suggested that subgroup patients with polymorphous light eruption may be elevated risk for lupus Juvenile spring appears to either variant closely related disorder. The presence of plasma cells would be in favor latter condition. Other than demonstrating conspicuous and dilated rough endoplasmic reticulum within dermal fibroblasts electron microscopy merely serves to confirm light microscopic observation of widely separated fascicles collagen fibers

Reticular erythematous mucinosis infiltrate consists of mature lymphocytes with lesser number histiocytes. A clinical history of documentation resolution lesions with cessation light exposure may sometimes be the only way distinguish these entities

The collagen fibers are separated but appear morphologically normal. B cells are relatively sparse in number or absent. Clinically polymorphous light eruption resolves once exposure to sunlight has ceased contrast the persistent lesions of reticular erythematous mucinosis

In contrast cells predominate lymphocytic infiltrate of skin. An erythema gyratum repenslike eruption has also been described in association with Sj gren syndrome neutrophilic dermatosis vasculitis patients lupus erythematosus and setting of urticarial . The evidence available suggests that lymphocytic infiltrate of skin is distinctive dermatosis

Scaling occurs and there may be pruritus. However once the disease established persistence for many years common. The distribution of lesions often changes with time

Occasionally however CD suppressor T cells constitute the majority of . It is of course tempting to postulate that they are related but data support such conclusion not yet established

Perifollicular inflammation is not feature of polymorphous light eruption. IgMreactive papillary dermal cytoid bodies were documented in one case

In one study of patients also had lesions typical polymorphous light eruption. However more recent cases have documented erythema annulare centrifugum in patients with underlying malignancy once again raising issue of association neoplasia. However the lack of an agreedupon diagnostic gold standard makes this designation somewhat controversial

The patches in chronic superficial dermatitis tend to be uniform size shape and color contrasting vividly with greater variability of those mycosis fungoides. There is no evidence of systemic involvement. EpsteinBarr virus HIV herpes simplex and zoster molluscum contagiosum Fungal infection

The histological features of lupus erythematosus are sometimes difficult distinguish from polymorphous light eruption particularly when latter associated with positive However most cases negative testing. Rarely however the two diseases appear to coexist. Lesions often resolve within weeks or months but relapses are not uncommon and many patients the disorder persists for years
