Epidermoid Inclusion Cyst

AbstractEpidermoid bone inclusion cysts are pathological structures bordered by a layer of stratified squamous epithelium containing keratin debris. They are also called epidermal bone cysts. Intraosseous epidermoid cysts are rare entities; these lesions may occur as a result of trauma (puncture wound or pressure erosion).They appear to be well defined, translucent lytic lesions with sclerotic margins on imaging studies. The most frequent sites affected are: the distal phalanx and the calvaria - intradiploic, but a few cases of larger bone involvement have been reported. The imagistic differential diagnosis of this lesion includes intraosseous extension of a glomus tumor, enchondroma, osteoid osteoma, acral metastases, some primary vascular bone tumors, giant cell reparative granuloma, subungual nodular melanoma or other lytic non-neoplastic lesions such as osteomyelitis. We present the case of a 70-year-old man experiencing anxiety and pain due to distal phalanx expansion of the IV digit, following hand trauma. An X-ray was performed, showing a radiotransparent lesion located in the distal phalanx. An intramedullary inclusion cyst must be taken into account as a clinical differential diagnosis. Due to the extensive destruction of the distal phalanx, amputation was necessary. Gross examination of the surgical specimen revealed a cystic lesion that contained whitish, creamy material with extensive necrotic areas. Microscopic examination revealed a ruptured intraosseous epidermoid inclusion cyst, which was successfully excised.

Epidermoid Inclusion Cyst

Intraosseous epidermoid inclusion cysts are rare benign bone lesions that occur most commonly in the skull and in the distal phalanges of the fingers. Herein we report a case of an intraosseous epidermoid inclusion cyst occurring in the distal phalanx of the left hallux. Only six occurrences of this lesion have been described in the foot. This patient’s presentation, with active drainage (initially appearing as purulent discharge from an acutely tender ingrown hallux nail) and a known inoculation event accompanied by severe peripheral vascular disease, make this case unique.

Radiological Changes

Lesions of the distal phalanx often pose a radiological dilemma as the differential diagnosis is potentially broad. Particularly for lytic lesions, there is a concern whether an underlying primary tumor or a metastatic deposit is present. Bone tumors of the hand are infrequent when compared to soft tissue tumors, and those involving the distal phalanx are very rare. Lesions of the distal phalanx may arise secondary to benign or malignant pathologies and may reflect primary or secondary tumors. The most common benign lesion is an enchondroma while the most frequent primary malignant lesion is chondrosarcoma. Inflammatory, metabolic, autoimmune, and traumatic pathologies may also present with a wide spectrum of radiological changes involving the distal phalanx. It is these tumor-like mimics which can further complicate diagnosis. We hope to highlight distinguishing features between these entities, allowing the radiologist to generate a clinically useful differential diagnosis. Even though most lesions are benign, it is crucial to differentiate them as some may be the first presentation of more a systemic condition.

Portal vein thrombosis (PVT) can be chronic or acute in nature; it is characterized by a thrombus formation in the main portal vein and/or its right or left branches. Herein, we present a 36-year-old woman with asymptomatic noncirrhotic chronic PVT who developed preeclampsia in the later stage of pregnancy. This report will emphasize the clinical differential diagnosis, outcome, and management of pregnancies complicated by noncirrhotic PVT.

Benign Schwannoma

Summary Background Schwannoma is a benign tumor arising from Schwann cells of the peripheral nerves. It is often asymptomatic and can develop in the retroperitoneum, mediastinum, head and neck region, and upper and lower extremities. Schwannoma of the abdominal wall is extremely rare, but differential diagnosis with malignant neoplasms is important to reduce the risk of undertreatment. Methods A narrative review of abdominal wall schwannoma was performed using PubMed, EMBASE, and Web of Science database and the search terms “schwannoma”, “neurinoma”, “neurilemmoma”, “soft tissue tumors”, “neurogenic tumor”, “rectus abdominis mass”, “abdominal wall”. In addition, the hospital charts were reviewed to report the personal experience. Results Only 9 single case-reports of benign schwannoma of the abdominal wall were found in the English medical literature over the past decade. None of the patients received preoperative biopsy and all were resected with clear margins. In addition to the literature review, we report the case of a 58-year-old man referred for a palpable mass in the left upper abdominal quadrant. Ultrasonography and magnetic resonance imaging revealed a solid and well-encapsulated mass inside the left rectus abdominis muscle. A core biopsy of the lesion provided the diagnosis of cellular schwannoma and this was confirmed by histopathologic examination of the surgical specimen. Conclusions Benign schwannoma of the abdominal wall is extremely rare. Percutaneous core needle biopsy is important for the differential diagnosis with more common and biologically more aggressive malignancies, such as desmoid tumors and sarcomas, and may be relevant for planning the most appropriate management.

Epidermoid Inclusion Cyst

Abstract Epidermoid inclusion cysts are benign lesions that occasionally occur in the distal phalanges of the fingers but are less frequently identified and underreported in the toes. We describe a 55-year-old man with a history of work-related trauma followed by painful expansion of his right great toe, resulting in great anxiety. Imaging studies revealed a radiolucent lesion in the distal phalanx of his right hallux. Clinical differential diagnoses included the possibility of an intramedullary inclusion cyst and other various radiolucent lesions. During surgery, a cystic lesion that contained creamy material was discovered. Frozen section diagnosis of the lesion was an intraosseous epidermoid inclusion cyst. The lesion was removed and the patient recovered uneventfully. Although it has been reported that an unduly large number of phalangeal cysts have been treated by amputation, the judicious use of intraoperative frozen sections can prevent this scenario.
