Chronic urticaria due to Blastocystis hominis.

A 24-year-old woman had a 9-week history of second to third daily urticaria that began after an episode of contact urticaria to topical bufexamac. She was found to have an underlying gastrointestinal infection with Blastocystis hominis. This was thought to be clinically relevant as she had a history of mild chronic diarrhoea. After treatment of the Blastocystis hominis, her urticaria ceased. This could indicate the importance of performing stool microscopy and culture on all patients with chronic urticaria of unknown aetiology. The relationship of urticaria to intestinal parasites and the possibility that non-steroidal anti-inflammatory medications could act as cofactors that help precipitate an urticarial reaction is discussed.

Thermosensitive lichen amyloidosis.

BACKGROUND: A 26-year-old male presented with a 3-year history of lichen amyloidosis. On examination, there was a pigmented papular eruption with a ripple pattern affecting the limbs and trunk but sparing the axillae, antecubital and popliteal fossae, central chest, neck and face. There was also prominent sparing of the skin overlying the superficial veins of the limbs. The sparing of the superficial veins of the limbs by lichen amyloidosis raised the possible role of cutaneous temperature in governing the distribution of amyloid deposits in our patient. OBSERVATIONS: Total body infrared thermography demonstrated consistent sparing of the amyloid deposits in areas with higher cutaneous temperatures such as the neck and axillae as well as the course of the superficial veins. The cooler areas such as the extensor surfaces of the arms and legs corresponded to areas of amyloid deposition. Narrow band ultraviolet B (NBUVB) phototherapy over a 5-month period resulted in a marked improvement of pruritus and clearing of the amyloid deposits. CONCLUSIONS: Our patient clearly demonstrated lichen amyloidosis in a thermosensitive distribution. This may be a gross manifestation of previous reports of in vitro thermosensitivity of amyloid fibril formation and may have potential implications in treatment at least in a subset of patients demonstrating this clinical feature.

Warfarin-induced skin necrosis associated with acquired protein C deficiency.

A 36-year-old woman developed skin necrosis of the inner thighs following the re-introduction of warfarin after a laparoscopic cholecystectomy. She had a history of liver disease and cardiomyopathy and was on warfarin for 10 years. Warfarin-induced skin necrosis secondary to protein C deficiency was diagnosed. Although warfarin was ceased immediately, the prothrombin time measurements remained prolonged and warfarin levels remained therapeutic. Our patient, who had attached great significance to warfarin therapy, had continued the ingestion of warfarin despite our advice. She required three surgical debridements. Protein C levels, as measured 1 year later, were within normal limits, confirming the transient nature of the acquired deficiency during the acute event. This is the second reported case of warfarin necrosis associated with acquired protein C deficiency.

Multiple hereditary glomangiomas: successful treatment with sclerotherapy.

Glomangiomas are characterized by cavernous vascular channels surrounded by glomus cells. Multiple glomangiomas, although usually painless, can be a few centimetres in size and appear as blue phlebectatic lesions. Surgical excision of multiple glomangiomas can lead to scarring and recurrences. Laser treatment using vascular lasers and CO2 lasers has been useful in small, superficial lesions. We present the successful sclerotherapy treatment of multiple glomangiomas using sodium tetradecyl sulphate in a 59-year-old man who presented with postoperative recurrence of multiple lesions.
