Primary paranasal Aspergillus granuloma in Saudi Arabia.

Respiratory aspergillosis has been described in many parts of the world; but primary paranasal aspergillus granuloma (PPAG), a recognised, distinct entity, has been described almost exclusively in Africa--specifically in the Sudan. The first case of PPAG in Saudi Arabia with bilateral involvement of paranasal sinuses is described. In view of the geographical similarities between Northern Sudan and Saudi Arabia, it is suggested that some of the granulomatous inflammatory conditions occurring in Saudi Arabia for which no definite aetiological agent has been ascribed may fall into this category. Increased awareness of the condition, together with the use of serological methods currently in use in the Sudan may help in defining the condition properly in this locality.

Nasopharyngeal carcinoma. A comparative study.

A comparative study of Ghanaian and Saudi hospital cases of nasopharyngeal carcinoma (NPC) shows a higher occurrence among younger subjects in the Ghanaian group, with the peak age incidence in the Saudi group being similar to those reported from other parts of the world. In view of the known high prevalence of Burkitt's lymphoma among Ghanaian children, it is suggested that the much higher proportion of younger Ghanaian subjects with NPC may be related to early exposure to the Epstein-Barr virus which is known to be associated with both malignancies.

Histiocytic necrotising lymphadenitis (Kikuchi-Fujimoto disease) in Saudi Arabia.

Five cases of histiocytic necrotising lymphadenitis (Kikuchi-Fujimoto disease) are described. As the condition appears to be poorly recognised in Saudi Arabia, an extensive review of the histological features is presented, in order to improve pathologists' awareness and to minimise the risk of diagnosing prognostically less favourable conditions such as malignant lymphoma. Etiologic and pathogenetic features of the disease are also discussed.
