Idiopathic vulvar calcinosis: the counterpart of idiopathic scrotal calcinosis

ULTRASOUND IMAGING AND PATHOLOGIC FEATURES OF IDIOPATHIC SCROTAL CALCINOSIS IN A YOUNG ADULT NIGERIAN AND REVIEW OF THE LITERATURE

Background

Idiopathic scrotal calcinosis is a rare and benign disease of the scrotal skin that presents as solitary or multiple painless calcified nodules or papules in the absence of systemic disorders of calcium or phosphorus metabolism. Although some theories have been proposed as to the cause of this rare disease, the exact cause remains unknown. In a resource-poor medical setting like Nigeria, a confident diagnosis of this condition can be made with ultrasonography.

Objective

The objective of this report is to emphasize the role of ultrasound in the imaging diagnosis of idiopathic scrotal calcinosis.

Case Presentation

This is a case report of a 38-year-old man who presented with recently discharging but longstanding multiple painless scrotal nodules of 22-years duration.

Conclusion

This case illustrates the prompt and accurate diagnosis of idiopathic scrotal calcinosis using an ultrasound, a readily available imaging modality in a low-resource setting.Although histology remains the gold-standard for diagnosing idiopathic scrotal calcinosis following surgical excision, this benign disorder has unique sonographic characteristics that could aid the radiologist in making a confident diagnosis.

Idiopathic calcinosis cutis of the vulva

Background:

In the present study, calcinosis cutis (CC) is defined as the deposition of amorphous calcium and phosphate salts under epidermis and it may be caused by a pre-existing event such as extravasation injury or hypercalcemic conditions. Idiopathic CC cases have no underlying disease or pre-existing cause.

Aim:

A demostrative vulvar idiopathic CC case presentation and review of the related literature.

Methods:

A 42-year-old multiparous female presented with vulvar nodular masses. She was keen on surgical removal of the lesions, as the masses caused dyscomfort during sexual intercourse. The lesions were removed and sent for histopathological examination. There was neither a history of trauma nor any inflammatory process in the vulvar skin prior to the development of lesions and no systemic abnormality was detected.

Results and Conclusions:

The histhopathologic evaluation of the biopsy specimen showed amorphous calcium deposits without any inflammatory infiltration in the dermis. There was no recurrence at 1 year's follow-up. This case shows that idiopathic CC may develop slowly at labio-vulvar region in a sexually active female with normal systemic or laboratory findings

Multiple sub-epidermal calcified nodule mimicking eruptive xanthoma: a case report and review of the literature

Sub-epidermal calcified nodule (SCN) is an uncommon form of idiopathic calcinosis. It usually occurs in children, particularly in the head and neck region, presenting as a solitary, painless, yellow-white nodule with papillomatous features. These lesions occur twice as common in males compared with females. The pathogenesis is uncertain, but the clinical and histological features of this lesion are distinctive. We report a case of 22-year-old man with multiple nodules bilaterally located on the dorsum of hands simulating eruptive xanthoma. Histopathological examination of one of the excised lesion confirmed the diagnosis showing epidermal and sub-epidermal deposition of calcium. This paper presents a review of the literature and adds a new case of SCN.

Scrotal calcinosis: a case report and review of pathogenesis and surgical management

Idiopathic scrotal calcinosis is an uncommon benign disorder of the scrotal skin which is characterized by multiple calcified intradermal nodules. We report a 33-year old with asymptomatic multiple calcified scrotal skin nodules. He had wide excision of the lesions and direct closure of the scrotum. We review the pathogenesis and surgical treatment options for this rare disease of the scrotum.
