Squamous cell papilloma-like presentation of multiple neurovascular hamartomas of the oral cavity

Significance Statement: Neurovascular hamartomas (NVH) is an uncommon tumor-like developmental anomaly. We hereby report the case of a 28-year-old woman presenting with multiple millimetric excrescences in the oral cavity that were clinically interpreted as squamous cell papilloma and histologically consistent with NVHs. Neurovascular hamartomas is rare in the oral cavity. To the best of our knowledge, multiple NVHs have never been reported at this site.

Virilizing Adrenocortical Carcinoma Resected With Negative Margins Treated With Surgery Alone

Adrenocortical carcinoma is a rare malignancy. A virilizing adrenocortical carcinoma is even more unique of a diagnosis. In this report, we present a rare case of this uncommon tumor with an interesting presentation, clearly documented physical exam changes over a span of at least 8 years, and a technically challenging case. We also briefly review the management of adrenocortical carcinoma. The tumor was successfully resected with no planned adjuvant treatment at this time. The patient had recurrence of menstrual cycle post-operatively and required no steroid supplementation.

Lipofibromatous hamartoma of a digital branch of the median nerve: a case report and review of the literature

Lipofibromatous hamartoma is an uncommon tumor that causes nerve enlargement due to fatty adipose tissue infiltration in peripheral nerves being the median nerve at the carpal tunnel the most commonly affected site, typically associated with macrodactyly. Here we present a case which affected a digital branch of the median nerve

Anorectal Melanoma - Brownish Black Mass Not Always a Hemorrhoid

The non-specific clinical symptoms of anorectal brownish-black mass do not help to differentiate colorectal cancer, hemorrhoids, rectal ulcers which result in a delayed diagnosis or lead to inadequate management of lethal anorectal melanoma. Primary malignant melanoma of the anorectal region is an uncommon tumor, constituting approximately 1% of anal canal tumors which may be misdiagnosed clinically as hemorrhoids. Because of aggressive behavior and poor prognosis, efficient and prompt diagnosis is required in these cases. We report the 2 cases of this rare tumor.

Parachordoma: a rare recurring case at a rare site

Parachordoma is an uncommon tumor of soft tissue and the orign is not clear. This soft tissue tumor resembles chordomas as well as extraskeletal myxoid chondrosarcomas and has only recently been fully characterized. Although it is considered a benign lesion, its behavior tends to be locally aggressive, with reports of a recurrence rate of up to 20% and of several cases of metastasis. In this article, we report a case of parachordoma in the neck with recurrence that we met in clinical works.
