Perianal pseudoverrucous papules and nodules.

Perianal pseudoverrucous papules and nodules (PPPN) is a rare entity attributed to chronic irritation. We came across this entity in a case of spina bifida. A 14 year old girl having spina bifida at L3 presented with complaints of multiple asymptomatic whitish lesions on the inner aspect of thighs and labia majora since early childhood. She had incontinence of stool and urine since birth. Cutaneous examination revealed multiple 3-12 mm flat topped moist papules, few verrucous nodules, some of these lesions coalesced to form plaques at the perianal area extending upto the labia majora. On histology marked epidermal hyperplasia and pale keratinocytes in the epidermis was seen. This confirmed the diagnosis of PPPN. This rare condition can be mistaken with sexually transmitted diseases leading to unnecessary investigations and treatment.

Indian Journal of Dermatology, Venereology, and Leprology | May-June 2013 | Vol 79 | Issue 3 436 the location that had not been reported before. An excisional biopsy was performed without imaging studies, such as X‐rays, computed tomography, and ultrasonography as the patient refused to take further studies. During surgery, we confirmed that the nodule was not attached to the underlying skull, and the mass located in the subcutaneous layer was easily excised. Histopathologic examination revealed an encapsulated nodule that was entirely composed of mature cartilage [Figure 1b]. Chondrocytes in lacunae had oblong nuclei of various size [Figure 1c]. There were no cytologic atypia, mitosis or necrosis. Based on the characteristic histopathologic features, the patient was diagnosed with extraskeletal chondroma of the scalp, and there were no signs of recurrence at 6 months from the excision.
