Ectopic Cilia

Ectopic cilia are extremely rare congenital anomalies in which eyelash follicles appear in an abnormal place on the eyelid, most typically on the lateral quadrant of the anterior surface of the upper eyelid. In the majority of cases, simple surgical excision of ectopic cilia is indicated because of its cosmetic aspect. There is usually no associated medical co-morbidity with this anomaly. The authors report an unusual case of ectopic cilia associated with an orbital dermoid cyst and sinus tract. A 3-year-old boy was initially diagnosed with ectopic cilia on the left upper eyelid. There was no history of inflammation or swelling of the eyelid. An ophthalmological examination revealed only 1 mm of ptosis; no proptosis, inferior displacement, or palpable orbital mass was present. During surgical excision of the ectopic cilia, a thin sinus tract was identified, leading posteriorly to the orbit. Magnetic resonance imaging performed after the excision showed a supraorbital extraconal mass just below the roof of the left orbit. A supraorbital 2-piece craniotomy was performed with total extirpation of the dermoid cyst. The cyst was removed en bloc without damage to the extraocular muscles, but the sinus tract could no longer be identified. Follow-up MRI was performed 6 months after surgery and showed no evidence of recurrence. A follow-up ophthalmological examination showed no signs of inferior displacement or proptosis. To the best of the authors’ knowledge, this case is the first reported instance of ectopic cilia associated with a dermoid cyst and sinus tract in which no typical clinical signs and symptoms of possible orbital pathology were present. This case highlights the value of radiological examination in all cases of ectopic cilia prior to surgical excision.

Abstract Prevotella species are gram-negative anaerobic commensal bacteria of the oropharynx, which frequently cause periodontal disease but are otherwise rarely implicated in serious bacterial infections. Cranial dermoid cysts are benign neoplasms that grow along the planes of the embryonic neural tube closure. In infants, they most commonly present in frontal locations, including periorbital, nasal, and within the anterior fontanelle. Although dermoid cysts are slow growing, usually uncomplicated, and easily treated definitively with surgical excision, cranial cysts located on the midline are associated with a higher risk for persistent dermal sinus tract with intracranial extension of the tumor. We describe a case of a 10-month-old male patient with an occipital midline dermoid cyst with intracranial extension, infected with Prevotella melaninogenica, and complicated by intracranial abscess formation and meningitis.This case highlights two unusual disease entities: the uncommon occipital location of a dermoid cyst, and complications of that cyst caused by a serious bacterial infection with a normal oral flora. We discuss the recommendation for neuroimaging prior to surgical excision of a midline dermoid cyst, given the risk for dermal sinus tract with intracranial communication. We also discuss potential mechanisms for bacterial inoculation of this cyst with Prevotella melaninogenica. This pathogen has not previously been reported as a complication of dermoid cysts.

Dermoid cysts are rare benign tumors that arise from ectopic epiblastic inclusions and account for 0.4% to 1.5% of all tumors. They are usually 1 to 5 cm in size and composed of a pasty semisolid material. The orbital dermoid cyst is the most common type. Dermoid cysts can also occur in the spinal cord, ovaries, and pancreas. We encountered a 24-year-old man with a dermoid cyst over the left sternoclavicular joint. He reported intermittent secretion of a white tofu-like exudate from an underlying congenital sinus tract since birth. The secretion had turned hemorrhagic for the last month and had been accompanied by progressive swelling and pruritus for 1 week. Ultrasonography and magnetic resonance imaging revealed characteristics of a dermoid cyst, and histopathological examination confirmed the diagnosis. The patient underwent surgical excision of the cyst under local anesthesia. The incision healed well with no postoperative complications. Considering that a dermoid cyst has the potential to become infected or progress into squamous cell carcinoma, its removal at an early stage is suggested. Few reports in the literature have described a dermoid cyst that secretes hemorrhagic contents from a congenital sinus tract. We present this case to provide a reference for clinicians.

Purpose: To present a young female patient with left anterior orbital leiomyoma that originates from the supraorbital neurovascular bundle. Case presentation: A 41-year-old female patient was admitted to our clinic with a complaint of swelling of the left upper eyelid. Based on the ophthalmological and imaging assessments, the excisional biopsy with the preliminary diagnosis of dermoid cyst was planned. The histopathological and immunohistochemical examinations of excised sample revealed surprisingly that the tumour was a leiomyoma. No recurrence was detected in the patient’s follow-up. Conclusion: Although it is rare, orbital leiomyoma should be considered in the differential diagnosis of patients with orbital tumour.

Dermoid cysts are among the most common periorbital and orbital tumors presenting in childhood. Several studies have shown that dermoid cysts may deform adjacent bones; however, few studies have followed the course of bone regeneration after the excision of a cyst. We report a case of a 29-month-old female infant who presented with a palpable mass over her right lateral eyebrow. Ultrasonography findings suggested a dermoid cyst, and computed tomography revealed a 2.1-cm round bony defect in the right zygoma. After surgical excision of the dermoid cyst, we successfully applied fibrin sealant to eliminate the dead space. Pathological findings showed nodular lesions with flat cystic walls containing lamellated keratin and sebaceous glands, supporting the diagnosis of dermoid cyst. At 6 months postoperatively, a follow-up computed tomography scan confirmed complete recovery of the bone defect in the right zygoma.

Epidermoid cysts are rare benign tumors developed from ectodermic inclusions. They usually sit at the ponto-cerebellar angle, the para-sellar region and the temporal fossa. Their seat at the fourth ventricle is unusual. We report two cases of squamous cell cyst in two young patients aged 21 and 33 admitted for intracranial hypertension syndrome associated with walking disorders. The diagnosis of epidermoid cyst of the V4 was evoked on the data of the MRI then confirmed in peroperative and in histology. The surgical excision was subtotal due to adhesion of the capsule to the upper part of the V4 floor. After a 12-month follow-up, the first patient showed no signs of tumor re-evolution. The second patient benefited from a ventriculo-peritonial derivation 45 days after the cyst was removed. After a 7-month follow-up, the patient showed no clinical signs suggestive of tumor re-evolution.

An 11-year-old cat presented for evaluation of intermittent vomiting, constipation and hyporexia of 3 weeks duration. Ultrasonographic and endoscopic examination revealed a soft tissue mass adjacent to the lower gastro-esophageal sphincter. Surgical excision of the mass was successfully performed resulting in a resolution of clinical signs. Histologically the mass was consistent with a smooth muscle hamartoma. At follow-up 7 months after surgery, the cat remained free from clinical signs.

Abstract Background Ganglioneuroblastoma (GNB) is a neoplasm that arises from the primitive cells of the sympathetic nervous system during childhood. The current case is very unique because of the initial primary tumor manifestation in the orbit and an adrenal tumor being observed later during follow-up. Case presentation A 2-year-old girl presented to the Ophthalmology Department of our hospital complaining of swelling of the left upper eyelid for approximately one month. Orbital computed tomography (CT) revealed a left orbital mass with bone destruction. Thoracic and abdominal CT indicated no abnormalities. The mass was surgically resected, and histopathological analysis confirmed it as GNB. During follow-up, abdominal CT detected an adrenal tumor with internal calcification, a calcified nodule on the left side of the abdominal aorta, and mesenteric lymph nodes. Accordingly, primary orbital GNB and metastatic adrenal GNB were the possible considerations. We removed the adrenal tumor, and the patient underwent chemotherapy. However, the patient died 18 months after the ophthalmic surgery. Conclusion Primary orbital GNB in children is easily misdiagnosed because of its rare occurrence and atypical clinical findings. Imaging methods combined with histopathological examination contribute to the detection and diagnosis of primary and metastatic GNBs. Thus, timely surgery combined with adjuvant chemotherapy and long-term follow-up is essential for controlling the metastasis of GNB and improving the survival rate of patients.

Abstract Myoid angioendothelioma (MA) represents an extremely rare nonhaematopoietic proliferation of the spleen. MA is a rare, benign, vascular tumour that consists of vascular elements and arranged stromal cells. Due to an absence of specific clinical signs and symptoms, MA is considered challenging to diagnose. Although the radiological presentation can indicate the vascular nature of the tumour, the diagnosis of MA is almost exclusively obtained from the use of histopathology after surgical excision and immunohistochemistry of the tissue. Due to its completely unclear biological behaviour and relationship with other primary and secondary tumours, the only effective therapy for MA is splenectomy and a regular postoperative follow-up. Herein, we report a case of a 26-year-old male patient with nonspecific abdominal pain and a radiologically detected tumour of the spleen who underwent a laparoscopic splenectomy. Histopathologic and immunohistochemical examinations confirmed a myoid angioendothelioma of the spleen.

Epidermoid cysts are slow-growing congenital tumors developed from ectodermal inclusions. They usually sit at the cerebellopontine angle or basal cistern, their location in the fourth ventricle are exceptional.We report the case of a 44-year-old patient admitted to the Neurosurgery department for chronic daily headaches with visual impairment recently aggravated by cerebellar stato-kinetic syndrome.The diagnosis of epidermoid cyst of the fourth ventricle was suspected on MRI especially in diffusion sequence and then confirmed by the anatomopatological studies. Subtotal surgical excision was performed. The evolution was marked by the disappearance of clinical signs. Radiological and clinical follow up were indicated.
