The Colposcopic Atlas of Schistosomiasis in the Lower Female Genital Tract Based on Studies in Malawi, Zimbabwe, Madagascar and South Africa
Figure 24
Grainy sandy patches and trichomoniasis together.
Clusters of grains on the posterior lip of the ectocervix are both superficial and deep, millimetres to centimetres from the squamo-columnar junction (dashed line). This case is however also positive for Trichomonas vaginalis and an erythematous surface is seen with microscopic, punctate haemorrhages typical for trichomoniasis (the so-called ‘strawberry patches’). We also see fresh blood from the mucosal surface. Both diseases may cause such inflammation.
