Neck masses in children can be inflammatory, congenital or neoplastic. When a congenital cyst becomes infected repeatedly, it may mimic inflammatory disease and the diagnosis may be challenging with ultrasound. An increasing incidence of infection with non-tuberculous mycobacterial organisms has been observed in recent decades in children with cervical lymphadenopathy. An ultrasound scan performed during the infectious phase of a mass can be misleading and can lead to an incorrect diagnostic hypothesis with the risk of erroneous medical and surgical therapies...

BACKGROUND: Seborrheic keratosis (SK) is the most common benign epidermal tumor of the skin. Even though SK has been well characterized clinically, dermoscopically, and histopathologically, data regarding clinical dermoscopic and histopathological correlation of different types of SK are inadequate. AIM: We carried out this study to establish any correlation between the clinical, dermoscopic, and histopathological appearance of SK and its variants. METHODS: This was a descriptive study...

BACKGROUND: Circumcision is a common minor surgical procedure and it is performed to a varying extent across countries and religions. Despite being a minor surgical procedure, major complications may result from it. In Ghana, although commonly practiced, circumcision-related injuries have not been well documented. This study is to describe the scope of circumcision-related injuries seen at the Komfo Anokye Teaching Hospital in Kumasi, Ghana. METHODS: The study was conducted at the Urology Unit of the Komfo Anokye Teaching Hospital in Kumasi...

Malignant transformation of epidermal cyst is rare, with most cases arising in the head and neck. Here, we report a case of squamous cell carcinoma arising from a longstanding epidermal cyst in the right vulva of a 65-year-old woman. The patient presented with a sudden increase in size of the cyst over 6 weeks to the size of a golf ball. Excisional biopsy and histology indicated moderately differentiated squamous cell carcinoma within an epidermal cyst (FIGO stage IB). Strong p16 immunopositivity was also demonstrated and the potential significance of this is discussed...

Epidermal cyst is a benign tumor that grows slowly and develops from entrapment of epidermis into the dermis. Inguinal canal is an extremely unusual location for an epidermal cyst in children. Here in, a 6-year-old girl presenting with inguinal mass which was diagnosed to be epidermal cyst in the patent processus vaginalis sac is reported. To the best of our knowledge, it is the first case of epidermal cyst in the patent processus vaginalis in a child.

Unlike its family member p53, TP63 is rarely mutated in human cancer. However, ΔNp63α protein levels are often elevated in tumors of epithelial origin, such as squamous cell carcinoma and cholangiocarcinoma. To study the oncogenic properties of ΔNp63α in vivo, we generated transgenic mice overexpressing ΔNp63α from the Rosa26 locus promoter controlled by keratin 5-Cre. We found that these mice spontaneously develop epidermal cysts and ectopic ΔNp63α expression in the bile duct epithelium that leads to dilatation of the intrahepatic biliary ducts, to hepatic cyst formation and bile duct adenoma...

Merkel cell carcinoma is a rare aggressive primary cutaneous neuroendocrine tumor. It is associated mostly with malignant skin lesions. Rare cases in the literature described its association with benign skin adnexal lesions. We present here an additional case of Merkel cell carcinoma arising from an epidermal cyst located in the left arm of a 57-year-old male. The tumor was composed of lobules of monotonous round cells with dusty chromatin. It was positive for cytokeratin 20 and neuroendocrine markers. Patient was treated with surgical resection and radiation to the axilla...

OBJECTIVE: Dermoid and epidermoid cysts rank among the most common pediatric tumors. We analyzed the outcomes of surgical excision of dermal and epidermal inclusion cysts in a large consecutive series of children. METHODS: We retrospectively reviewed 128 consecutive children who underwent calvarial inclusion cyst resection between 2000 and 2010 at NYU Langone Medical Center. Demographic information, neurological exam, lesion location, lesion diameter, type of treatment, extent of resection, time of follow-up, and recurrence were collected...

Cysts and fistulae of the face and neck in children are formed before birth and correspond to the persistence of embryonic remnants that occur due to coalescence defects of embryonic buds or due to epidermal inclusion. They represent the most common pathological malformation of the face and neck. They may be separated according to their location into laterocervical cysts and fistulas or median cysts and fistulas. Their discovery may occur prematurely at birth or later during growth or in adulthood. Their treatment always requires surgical excision, which must be complete in order to prevent recurrences...

OBJECTIVE: Apart from the "common" lesions (e.g. pituitary adenomas, Rathke's cleft cysts, meningiomas and craniopharyngiomas), there is a plethora of rare tumors or tumor-mimicking lesions in the sellar and suprasellar region (SSR). Due to a lack of characteristic imaging features, there is a dilemma in distinguishing these rare lesions from the more "common" ones preoperatively. Consequently, both diagnosis and definition of surgical goals, as well as further treatment strategies continue to be challenging for all attending physicians...

Seborrheic keratoses (SKs) are common epidermal tumors composed of benign keratinocytes. Malignant skin tumors including basal cell carcinoma (BCC) rarely arise within SKs. We report a rare case of an 82-year-old man with nodulocystic BCC that appeared at the center of a scaly hyperpigmented SK that had been presented for more than 10 years. It was histologically confirmed that CK19-positive BCC arose directly from the wall of the pseudohorn cyst, a part of the SK. Nodular and/or cystic BCC also rarely arise within SKs while the most common histologic type of BCC within SKs is the superficial type...

Eccrine tumors are adnexal tumors with a varied clinical presentation and wide histological spectrum. This study aims to consolidate data on the clinical characteristics of eccrine tumors to help improve clinical acumen and management of such tumors. Histopathological records from January 2008 to December 2012 were retrieved. Clinical characteristics of the tumor including site, appearance, symptoms, color, duration prior to presentation, and clinical and histological diagnosis were recorded. Eighty-four patients with eccrine tumors were identified, with seven main types of tumors recognized-hidradenoma (33...

Epidermal cysts also known as epidermoid cysts, is one of the common benign tumours presenting anywhere in the body. However, epidermal cyst in the penis is very rare. This condition in children is usually congenital due to abnormal embryologic closure of the median raphe; hence, it is termed as median raphe cysts (MRCs). Penile epidermal cysts may occur in adults following trauma or surgery due to epidermal elements being trapped within closed space. During wound healing, trapped squamous epithelium, undergoing keratinisation leads to cyst formation...

Epidermal inclusion cysts are benign cutaneous lesions caused by dermal or subdermal implantation and proliferation of epidermal squamous epithelium as a result of trauma or surgery. They are typically located on the scalp, face, trunk, neck, or back; however they can be found anywhere on the body. Lesions are asymptomatic unless complicated by rupture, malignant transformation to squamous cell carcinoma, or infection at which point they can clinically appear as more sinister pathologies. We present the case of a 45-year-old laborer with a ruptured epidermal inclusion cyst, manifesting clinically and radiographically as a malignancy...

Pilonidal sinus is a chronic inflammatory disease commonly observed in the sacrococcygeal region. The authors report a patient of a pilonidal sinus in a rare location-the lateral orbital region. The authors' patient was misdiagnosed with an epidermal cyst, and the subsequent incomplete excision of the sinus tract led a pilonidal sinus with a high morbidity resulting in the destruction of bone tissue in the lateral orbital wall. It was, therefore, crucial to accurately diagnose and treat before the infection progressed through the bone and caused osteomyelitis...

Lesions on the scalp are frequently encountered in clinical practice. Commonly diagnosed lesions include epidermal inclusion cysts (EICs), dermoid cysts and lipomas. Dermatofibrosarcoma protuberans (DFSP) is a low-grade malignant skin tumour occurring mostly in the extremities. However, its occurrence on the scalp is unusual, with an incidence of <5%. This lesion is rarely known to undergo fibrosarcomatous transformation. We present two such rare cases of DFSP of the scalp, with fibrosarcomatous transformation, masquerading clinically as EIC...

The incidence of epidermoid tumors is between 1% and 2% of all intracranial tumors. The usual locations of epidermoid tumor are the parasellar region and cerebellopontine angle, and it is less commonly located in sylvian fissure, suprasellar region, cerebral and cerebellar hemispheres, and lateral and fourth ventricles. Epidermoid cysts located in the posterior fossa usually arise in the lateral subarachnoid cisterns, and those located in the brain stem are rare. These epidermoids contain cheesy and flaky white soft putty like contents...
