Isothipendyl chlorhydrate is an azaphenothiazine, an active ingredient of an antipruriginous gel, Apaisyl gel® (Merck Médication Familiale, Dijon, France). Although Apaisyl gel is registered and used worldwide, we present the first case of contact photoallergy to isothipendyl chlorhydrate to our knowledge. The diagnosis suspected on the basis of a positive UVA photopatch test to chlorpromazine was confirmed by a strongly positive UVA Apaisyl gel photopatch test and our photophysical studies. This case confirms the need to keep the phenothiazines in the photopatch test standard series as a diagnostic marker of phenothiazine photoallergy.

BACKGROUND: Recurrent breast cellulitis has been described as a complication following breast conservation therapy. OBSERVATION: A 50-year-old woman undergoing tumour excision, postoperative radiotherapy and chemotherapy presented recurrent breast cellulitis in the same region. The presence of lymphangiectasia suggested a complication subsequent to lymph stasis. DISCUSSION: Conservative therapy for breast cancer, allowing the development of subclinical or patent lymphÅdema, constitutes a prominent risk factor for recurrent cellulitis. This complication has also been considered in patients with lower extremity cellulitis following saphenous venectomy for coronary bypass surgery. The unusual presence of lymphangiectasia observed in our patient provides clear evidence that lymphÅdema is the most prominent risk factor for the development of cellulitis after breast conservation therapy.

BACKGROUND: Dirofilariasis is an autochthonous disease caused by Dirofilaria (Nochtiella) repens, a subcutaneous parasite of dogs and other carnivorous animals. Human infection leads to a self-limiting disease that generally presents clinically as a subcutaneous nodule. We describe a case occurring outside the classical endemic Mediterranean region. PATIENTS AND METHODS: A 38-year-old woman presented with a scalp nodule present for six months. Surgery revealed a thread-like parasite identified as a female Dirofilaria repens without microfilariae. DISCUSSION: This case points to the spread of this disease to temperate areas beyond the regions classically affected.
