Pityriasis lichenoides chronica is characterized by unknown etiology, chronicity and by being essentially asymptomatic and refractory to therapy. Nine patients with pityriasis lichenoides chronica were treated with orally administrated 8-Methoxypsoralen and UVA irradiation(PUVA Therapy). After S-45 PUVA treatments, lesions were completely cleared.

We report herein a case of pityriasis lichenoides et variloiformis acuta in a 48- year-old man, who has wide spread erythematous macule, papule, vesicle, hemorrhagic vesicle and reddish-brown crust on the neck, trunk, axillae and both extremities. He was treated successfully with tetracycline 2. 0 gm a day for 4 weeks.

A lg year-old female patient with pityriasis lichenoides et varioliforrnis acuta (PLEVA) was been treated with PUVA, At first, she was treated with tetracycline for 8 weeks with improvement somewhat. But 2 months later, her skin lesions aggravated slowly. So, we tried to treated her with PUVA and then she was cleared completely. The initial dose of UVA was 5 J/cm The UVA dosage increased by 10g of the previous exposure and increased to the maximum dose, 15 J/cm The patient exposed to UVA R times per week. 12 times after the PUVA therapy, the skin lesions begin to improve and completely improved at 21 times of Pl.JVA therapy. She was followed up every week and there was no side effect except hyperpigrnentation till 24 months. The total dose during treatment is 210 J/cm.

BACKGROUND: Pityriasis rosea is an acute inflammatory dermatosis with an unproven etiology. The typical clinical feature consists of an initial, single herald patch followed by development of smaller, disseminated, papulosquamous, ovoid macules. However, an unusual papular type of pityriasis rosea is relatively common in children and it shows similar clinical characteristics to pityriasis lichenoides. OBJECTIVES: Our purpose was to observe the clinical and histologic features of pityriasis rosea and pityriasis lichenoides, and differentiate two diseases in children. METHODS: Sixteen children with pityriasis rosea and nineteen children with pityriasis lichenoides were investigated clinically and histologically. RESULTS: 1. Clinically, pityriasis rosea may be differentiated from pityriasis lichenoides by the existence of herald patch, short duration, the uniformity of size and shape, and residual pigmentation. 2. Focal parakeratosis, intraepidermal vesicle and papillary derma edema are more common in pityriasis rosea. In contrast, deep dermal infiltration, dyskeratosis, epidermal necrosis and confluent parakeratosis are more common in pityriasis lichenoides. 3. Comparing to the plaque type, a papular type of pityriasis rosea shows more involvement in the extremities with longer duration. Histologically, parakeratosis and papillary dermal edema are less and spongiosis is more commonly observed in papular type. CONCLUSIONS: Pityriasis rosea in children often shows papules especially on the extremities, similar to that of pityriasis lichenoides. However, from the results in this study, we believe that two diseases can be differentiated if both clinical and histologic findings are carefully studied.

Febrile ulceronecrotic Mucha-Habermann's disease (FUMHD) is an unusual severe form of pityriasis lichenoides et varioliformis acuta (PLEVA) characterized by abrupt onset of widespread ulceronecrotic cutaneous eruption associated with high fever and systemic symptoms. In most cases, a mild typical form of PLEVA was usually present prior to the acute fulminating course. We report a case of FUMHD in a 6-month-old infant, who presented widespread hemorrhagic papules and coalescent thickly crusted ulcerations, high fever, liver dysfunction, and diarrhea with histopathologic findings suggestive of PLEVA.

Febrile ulceronecrotic PLEVA is an unusually severe from of PLEVA, characterized by the sudden onset of diffuse ulceronecrotic eruption aasociated with high fever. A mild eruption precede the acute fulminating course, We observed a 13-year-old boy presenting the form of febrile ulceronecrotic PLEVA. The histologic features were those of PLEVA. He received the systemic corticosteroids with aupportive care. To recognize this disorder is important because of a possibly fatal outcome, So close attention and vigorous therapy are necessary.
