We report the case of a 32-year-old woman who had pruritic urticarial skin lesions associated with episodes of arthralgia. The first site affected by the eruption was the inside surface of the thighs; the patient also reported the presence of leukorrhea. The woman had previously been treated with H1 antagonist with moderate and transitory results; skin lesions reappeared just after the interruption of the treatment. Her biochemical data showed increased levels of erythrocyte sedimentation rate, blood eosinophilia and hypocomplementemia. Antinuclear antibodies, rheumatoid factor, cryoglobulins and serological diagnosis for hepatitis or mononucleosis viruses resulted negative. Considering the initial site of the cutaneous features and the presence of leukorrhea, we requested a vaginal smear and a culture of the cervical secretion, which revealed the presence of a Trichomonas infection. Furthermore, the SDS-PAGE revealed the presence of a molecular mass of 230,000 Da (230-kDa) in the serum, which indicated a Trichomonas surface protein. The following treatment with oral metronidazole caused the eradication of the Trichomonas infection after 3 weeks and subsequently the resolution of the urticarial clinical features. We wish to underline that in the presence of a case of urticaria vasculitis syndrome which seems to be without cause, it is important to investigate every diagnostic suspicion scrupulously.

Dientamoeba fragilis is a pathogenic protozoan parasite with a world-wide distribution. Although originally described as an amoeboid organism, it has been reclassified as a flagellate, on the basis of a number of electron microscopic and immunological findings. Except for its lack of a flagellum, D. fragilis closely resembles Histomonas and Trichomonas. Interestingly, a resistant cyst stage has not been demonstrated and it is unlikely that its trophozoites can survive successfully outside the human host. As a consequence of its higher than anticipated coincidence of infection with Enterobius vermicularis, transmission may occur via ova of this pinworm. D. fragilis infection may be acute or chronic, and has been reported in both children and adults. The most common clinical symptoms include abdominal pain, persistent diarrhoea, loss of appetite, weight loss and flatulence. Occasionally, eosinophilia, urticaria and pruritus have been described. Demonstration of the characteristic nuclear structure of D. fragilis, needed for a definitive diagnosis, cannot be achieved in unstained faecal material; therefore, permanently stained smears are essential. Treatment is recommended in symptomatic cases, and iodoquinol, tetracycline and metronidazole have been used successfully.

Peripheral eosinophilia can be the presenting sign in many cutaneous diseases but is often missed as a marker of a serious undiagnosed underlying disease such as atopic dermatitis, urticaria, drug eruption, bullous pemphigoid, inflammatory bowel disease, helminthic infection, Churg-Strauss syndrome, rheumatoid arthritis, or lymphoma. We report a case of non-Hodgkin's lymphoma presenting as persistent eosinophilia with a diffuse nodular cutaneous eruption.

Despite treatment for malaria two travellers who acquired fever in Africa continued to have complaints: a 25-year-old Dutch woman and a 25-year-old Australian man. On questioning they appeared to have swum in Lake Malawi and a diagnosis of acute schistosomiasis was made, confirmed by serological tests. This syndrome, also called Katayama fever, is characterized by fever, oedema, urticaria and eosinophilia. The aetiology is not fully elucidated but it is supposed to be caused by immune complexes initiated by maturing worms and eggs. Patients who acquired fever in an endemic area must be questioned about contact with fresh water. Serological tests are important for the diagnosis. Treatment is with praziquantel but it is advised to treat only after the acute phase. During the acute manifestations corticosteroids may be necessary. Prevention is by avoiding contact with infected water. There is no vaccine. The role of artemisinin drugs in prevention is currently being studied.

In ordinary urticaria, individual lesions disappear within 24 hours. We encountered 3 patients who showed urticarial reactions lasting more than 24 hours. In all patients, skin biopsy revealed interstitial dermal edema and a perivascular infiltration predominated by eosinophils, without immunoglobulins or complement deposition, or endothelial fibrinoid degeneration. Their eosinophil counts and serum complement levels were within normal range. No proteinurea or joint pain was observed. They could not be controlled by any medications except for glucocorticoid. These findings indicate our cases are not ordinary urticaria, urticarial reaction accompanied by eosinophilia, urticarial vasculitis or delayed pressure urticaria. We recognize such urticarial reaction as a different clinical entity from the usual urticaria, and we speculate that this condition is caused by late phase reaction because of the clinical course and eosinophil infiltrations.

The syndrome of episodic angioedema associated with eosinophilia (EAE), originally identified by Gleich et al., is characterized by recurrent attacks of angioedema, urticaria, fever, increased body weight, and eosinophilia of unknown origin. Five young (aged 23-32 years) female patients were referred to our hospital because of eosinophilia (4,900-10,400/microliter). The chief complaints in all patients were angioedema and pain in the lower extremities without urticaria. Fever and increased body weight were not evident in most of the patients. These clinical features resolved spontaneously within 3 months, and no recurrence was observed. These characteristics were consistent with nonepisodic-type EAE (NEAE), which was proposed by Chikama et al. and is observed frequently in Japan. The clinical characteristics of NEAE were studied in the present 5 cases and the 25 cases reported previously in Japan. This revealed some additional characteristics: 1) a tendency for occurrence in autumn, 2) arthritis and absence of urticaria in some patients, and 3) increased serum LDH levels in some cases. It is suggested that NEAE should be treated with antiallergic drugs or simply followed without treatment, because spontaneous remission is observed frequently.

Thirty-eight (designated as cases) of 60 Korean emigrants who consumed raw fresh water fish in Yangon, Myanmar developed migratory swellings and creeping eruptions on the back, abdomen, flank, and other cutaneous areas 1-10 weeks later. The symptoms included itching, nodule formation, fatigue, urticaria, fever, pain on the skin, and erythematous plaques. Skin biopsies of two cases revealed no parasites. However, the mean +/- SD peripheral blood eosinophilia among the cases was 6.3 +/- 6.5% (n = 29) and 9.0 +/- 9.8% (n = 26) in two examinations. An enzyme-linked immunosorbent assay of their serum samples, using Gnathostoma doloresi adult worms as the antigen, showed mean +/- SD optical densities of 0.47 +/- 0.29 (n = 28) and 0.32 +/- 0.20 (n = 30) in two examinations and 0.12 +/- 0.09 (n = 50) in healthy controls. Two advanced third-stage larvae of G. spinigerum were found in two of six catfish purchased at a local market in Yangon. The outbreak of the human infection is suggested to have been due to G. spinigerum, which is known to live out its life cycle in the Yangon area of Myanmar.

Antiallergic drugs and antihistamines have been widely used for controlling mucosal allergic diseases in which eosinophilia is prominent. Although H1-receptor antagonists are effective for treating histamine-induced wheal and itch in urticaria, the effects of antihistamines and antiallergic agents on other eosinophilic skin diseases remain to be determined. We investigated the effects of oral administration of antiallergic drugs and antihistamines, such as suplatast tosilate, emedastine difumarate, and azelastine hydrochloride, on a novel murine model of eosinophilia in contact sensitivity to picryl chloride. Among the drugs tested, only suplatast tosilate remarkably inhibited blood and tissue eosinophilia and the ear swelling responses. The inhibitory effects on eosinophilia seemed to be mediated by the suppression of IL-5 production in spleen cells during eosinophil development, while the effects on the ear swelling response seemed to be mediated by suppression of IL-4 production in immune lymph node cells in the efferent phase. Suplatast tosilate may effectively treat eosinophilic skin diseases in which Th2-cell-derived cytokines are predominant.

Peripheral blood eosinophilia and eosinophilic tissue infiltration characterize the hypereosinophilic syndrome, which if untreated can be fatal. Its manifestations are protean. Often a diagnosis of exclusion, it presents diagnostic challenges. A fatal case of hypereosinophilic syndrome in a 16-year-old girl with petechiae, edema, urticaria, and diffuse erythema unfolded over 2 weeks. The histopathology of the petechiae demonstrated an eosinophilic and mixed cell interstitial and perivascular infiltrate and microthrombi in vessels. There was no evidence of T-cell clonality. Despite treatment with cyclosporine and methylprednisolone, she died. The age group; fulminant, fatal course without neoplasia; striking eosinophilia; and petechial rash are notable.

On March 16, 2000, a 37-year-old male was admitted to another hospital for fever, erythema of the limbs, and swelling of the right lower leg. The leukocyte count was 19,800/microliter, and the ratio of eosinophils was 61%, suggesting marked eosinophilia. Thoracic computed tomography (CT) revealed pneumonia in the left lung. However, the patient was negative for autoantibodies or parasitic antibodies. Administration of prednisolone at 80 mg/day resulted in a marked improvement of the symptoms and the eosinophilia. For diagnosis, detailed examination, and treatment, the patient was referred and admitted to our department on March 28. The dose of prednisolone was gradually decreased. On April 15, the agent was discontinued. Eosinophilia was not observed, however erythema of the limbs and swelling of the right lower leg recurred. Skin biopsy revealed in mild edema of the corium and eosinophilic infiltration, suggesting episodic angioedema associated with eosinophilia (EAE). In 1984, Greich et al. reported 4 patients with repeated angioedema, hives, and marked eosinophilia, and proposed the term EAE. Since then, more than 50 patients have been reported in Japan. Only 4 of these patients were males. We report on the present male patient together with the pathological findings.
