Clinicopathological characteristics of ocular surface squamous neoplasia: a 10-year review form a referral tertiary centre in Nigeria.

Background: Ocular surface squamous neoplasia (OSSN) is a heterogeneous group of proliferative squamous lesions on the ocular surface with varying biologic behaviours. This study aims to report the clinical profile and pathological characteristics of cases of OSSN seen at a tertiary referral centre in North West Nigeria.

Methods: A retrospective review of all cases of OSSN diagnosed over a 10-year period was done.

Cutaneous umbilical metastases in post-menopausal females with gynaecological malignancies.

Gynaecological malignancies frequently metastasize to contiguous structures, internal organs and bones. Cutaneous metastasis as a primary or recurrent presentation of these malignancies is rare and only a few cases have been reported in the literature. A twenty year (1991-2010) retrospective search for umbilical metastasis from gynaecological malignancies in our departmental case records showed only four cases.

Yolk sac tumour of the penile shaft: a rare primary extra-gonadal presentation.

Germ cell tumours (GCTs) commonly involve the ovaries, testes, and other midline structures in children and adolescents and comprised a variety of tumours that have a common histiogenetic origin. The yolk sac tumour (YST) variant is the most common one seen in over 80% of testicular GCTs in children. Other sites of occurrence of these tumours include the mediastinum, prostate, retroperitoneum, and sacrococcygeal region.
