In addition, other more common pruritic diseases such as pigmented contact dermatitis, pityrosporum folliculitis, parapsoriasis
, neurodermatitis and primitive cutaneous amyloidosis should be excluded prior to diagnosing a patient with NP, which is commonly a clinical diagnosis of exclusion (6).
Colloid milia in 3 cases (1.5%); 2 (1%) cases each of Lichen amyloidosis and Lichen sclerosus et atrophicus was seen; 1 (0.5%) each case of Parapsoriasis
, Favre-Racouchot Syndrome, Pruritus ani, Pyogenic Granuloma, Lupus Profundus were seen, 2 (1%) cases each of reactive perforating collagenosis and granuloma annulare and 3 (1.5%) cases of polymorphous light eruptions.
Features mimicking persistent gyrate erythema, lichen planus, parapsoriasis
lichenoides and varioliformis acuta, erythema exudativum, psoriasis, pustular psoriasis, histiocytoma, and sarcoidosis have been described (4).
'Deck chair sign' (DCS) is the sparing of flexures and skin folds, such as those of abdomen, antecubital and axillary areas which is usually observed in many inflammatory dermatoses, and was first described in papuloerythroderma of Ofuji (PEO).1 The sign is typical but nonspecific as it has also been described in several other conditions like, Waldenstorm's macroglobulinemia, angioimmunoblastic T-cell lymphoma, drug-induced erythroderma, mycosis fungoides, acanthosis nigricans, discoid lupus erythematosus, acute contact dermatitis and large plaque parapsoriasis
.2,3,4 We herein, describe a case of lepromatous leprosy with deck chair sign, which is very infrequently mentioned in literature.5
Poikilodermatous mycosis fungoides is a rare distinct clinical variant of cutaneous T-cell lymphoma (CTCL), formerly referred to as poikiloderma vasculare atrophicans or parapsoriasis
The secondary syphilides may appear like any dermatological diseases, such as lichen planus, psoriasis, parapsoriasis
, seborrheic dermatitis, acne vulgaris, impetigo, scabies, condylomata acuminata, etc--all of this making the clinical diagnosis quite difficult.
Guttate parapsoriasis/digitate dermatosis (small plaque parapsoriasis
) is mycosis fungoides.
revealed that the number of Ki-67 positive cells within the dermis was significantly higher in stage IIB-IV MF (22.3%) and lymphomatoid papulosis (26.3%) than stage I-IIA MF (4.3%) and parapsoriasis
Serious adverse event possibly related to treatment included suspected salmonellosis, abnormal liver function tests, and parapsoriasis
. Despite these impressive results, leflunomide did not receive FDA approval for JIA, due to concerns regarding inadequate plasma concentrations of its M1 active metabolite in children less than 40 kg.
