Chediak-Higashi syndrome in Chinese has not been previously reported in the English literature. A 14-month Chinese girl who presented with partial oculocutaneous albinism and Pseudomonas infection was found to have the classical intracytoplasmic inclusion bodies in the leucocytes by light and electron microscopy. Other characteristic features typical of this syndrome included hepatosplenomegaly, defective chemotaxis, and coarse but sparse melanin granules in hair shaft. She was also found to have hypertriglyceridaemia, a rare lipid abnormality occasionally reported in children suffering from this syndrome. Despite vigorous therapy with high dose ascorbate, corticosteroid and intravenous antibiotics, she died in the accelerated phase of Pseudomonas septicaemia.

We present a case of a 30-year-old woman with learning difficulties who was found dead at home by her mother. Her body was partially naked and covered in a number of unusual skin lesions with a targetoid appearance with red erythematous centers and well-delineated halos of pallor. These lesions were initially thought to be bruises by the police and by a forensic postmortem instigated. Postmortem examination also identified hepatosplenomegaly, severe lymphadenopathy, and focal patchy colonic ulceration. Histologic examination of the skin and bowel ulcers showed the lesions to be areas of infarction caused by Pseudomonas aeruginosa vasculitis. Pseudomonas was also cultured from the swabs of the abdomen, the spleen, and the blood cultures. Histologic findings of the lymph nodes showed complete effacement of the normal architecture by a population of pleomorphic small lymphoid cells. Immunohistochemistry confirmed the predominant cell type to be T-cells. The diagnosis of peripheral T-cell lymphoma was made. The cause of death was given as Pseudomonas septicemia secondary to immunocompromise resulting from the undiagnosed peripheral T-cell lymphoma. The pathogenesis of Pseudomonas and its association with malignancy is discussed along with a brief review of peripheral T-cell lymphomas. This case report demonstrates the characteristic macroscopic appearance of cutaneous Pseudomonas-associated lesions and how they can be misinterpreted as bruises.
