RESUMO

A 75-year-old man ingested salted fish guts made of Sagittated calamari which he caught in the daytime, with alcohol and then dozed. Five hours later, he woke up due to itching over his entire body and noticed generalized urticaria and a swollen tongue, which was too large for him to close his mouth. Serum total IgE was 456 IU/ml and ImmunoCAP was positive for anisakis, but negative for squid, shrimp, and ascaris. A skin prick test (SPT) was positive for anisakis extract (10 mg/ml) and house dust mites, but negative for squid and shrimp. He was diagnosed with IgE-mediated allergy due to Anisakis simplex after the ingestion of salted fish guts made of Sagittated calamari, which had been parasitized by Anisakis simplex. Furthermore, we performed SPT with six extracts of purified or recombinant allergens (Ani s 1, 3, 4, 5, 6, and 8) to identify the causative allergens in this case. Only Ani s 3 (tropomyosin) was positive, indicating that Ani s 3 was the causative allergen in this case. Third stage larvae of the nematode Anisakis simplex often parasitize not only marine fish but also invertebrates, including squid. It is necessary to consider Anisakis simplex allergy for urticarial reactions that develop after the ingestion of squid.

RESUMO

We describe a 4-year-old-girl with familial hemophagocytic lymphohistiocytosis (FHL) who developed disseminated cutaneous nontuberculous mycobacterial (NTM) infection after unrelated cord blood stem cell transplantation (uCBSCT). After transplantation, the patient developed steroid-refractory acute graft-versus-host disease, and was given methylprednisolone, cyclosporin and mycophenolate mofetil. Six months after uCBSCT, cutaneous lesions that looked like insect bites appeared and spread widely over the thighs. NTM infection was diagnosed by skin biopsy although no organism could be identified. Minocycline (MINO) and sulfamethoxazole/trimethoprim (ST) were administered. However, the cutaneous disease followed a course of remissions and exacerbations. One month after the skin biopsy, mycobacterium chelonae was detected by bacteriological culture of abscess drainage. Ten months after uCBSCT, the cutaneous lesions quickly progressed and the inguinal lymph nodes became enlarged and painful. Then the antibiotics were switched from MINO and ST to amikacin and clarithromycin (CAM) based on the results of mycobacterial susceptibility test. The cutaneous lesions gradually improved after continuous administration of CAM. Cutaneous NTM infection is rare, but it may occur in immunocompromised patients after SCT.
