A 59-year-old female living in Rayong Province, eastern Thailand, presented with painless, right upper eyelid nodule for 3 months. Upon removal of the eyelid mass, a well-circumscribed, firm globular mass with diameter about 1 cm was found. Histopathological examination revealed an immature female dirofilarial worm reminiscent of Dirofilaria repens, characterized by prominent sharp longitudinal ridges at external surface of the cuticle. Analysis of the mitochondrial 12S rRNA sequence showed that the worm belongs to Candidatus Dirofilaria hongkongensis. It is likely that some infections previously reported as D. repens based on histological examination may have actually been due to Candidatus D. hongkongensis.

ABSTRACT Invasive mycotic infections can be effectively treated if rapid identification of fungus is obtained. We reported a case of coinfection by Aspergillus and Rhizopus sp. involving nose, paranasal sinuses and orbit in a 51 years old male patient diagnosed as diabetic on admission. He presented to ENT OPD with history of drooping of right upper eyelid, decreased vision right eye and deviation of angle of mouth to left side for 12 days. NCCT nose, PNS and orbit showed soft tissue density in right maxillary sinus, ethmoids and destruction of right inferior turbinate. MRI of nose, PNS and orbit revealed hypointense density in right maxillary and ethmoid sinuses on T1-weighted images and on T2-weighted; it was hyperintense. Patient underwent endoscopic debridement under general anesthesia and tissue was sent for microbiological and histopathological examination which confirmed presence of Aspergillus and Rhizopus. Patient responded to therapy with IV amphotericin B and surgical debridement. On discharge patient's condition was good. How to cite this article Gupta R, Gupta B, Bal A, Gupta AK.

AbstractA case of the human ocular dirofilariosis in 72-year-old man from southern Slovakia is documented. Two days before visiting a doctor he noticed a live worm in his right eye. The eye was inflamed and itching. The worm of 100 mm in length was isolated from the subconjunctival space. On the basis of morphological appearance, histological examination and PCR-based detection, it was identified as Dirofilaria repens. The patient was probably infected in the southern Slovakia, which is an enzootic area of dirofilariosis of dogs.

Primary cutaneous mucinous carcinoma (PCMC) is a rare, low-grade malignant neoplasm of the sweat gland, whose history has been controversial regarding eccrine versus apocrine origin. This case report describes a 53-year-old male who presented to the University of Florida, Gainesville, ophthalmology clinic and was referred to the oculoplastics service with a painless, subcentimeter mass on the lateral right upper eyelid including the canthus, consistent with recurrent primary cutaneous mucinous carcinoma of the eyelid. Four years prior, the patient had undergone excisional biopsy of the lesion in a clinic, which revealed residual tumor, but the patient deferred further surgery at the time. The patient underwent surgical excision of the mass with reconstruction without operative complications and with negative surgical margins. PCMC is difficult to diagnose clinically due to its rarity and requires a histopathological examination for confirmation of the diagnosis. This report presents the first case in the literature of primary cutaneous mucinous carcinoma in a patient with human immunodeficiency virus (HIV). With this case report, we aim to raise awareness of primary cutaneous mucinous carcinoma as a potential part of the differential diagnosis for malignant eyelid lesions, including those present in patients with HIV.

Abstract Background Epibulbar complex choristoma, a rare congenital epibulbar tumor, has many diverse forms. Reviewing the literature, it can present clinically as either a circumferential or isolated epibulbar mass, limbal tumor, lateral canthal mass, aggregate of ectopic cilia in the upper eyelid, eyelid mass mimicking chalazion, or lacrimal caruncle mass. The management depends on the extent of involvement, the risk of amblyopia, and cosmetic concerns. Here, we report an atypical presentation of epibulbar complex choristoma with simultaneous eyelid involvement. Case presentation A 1-month-old full-term boy was brought to our clinic with congenital epibulbar mass of the right eye with simultaneous eyelid involvement. Dilated fundus examination was unremarkable. Survey for linear nevus sebaceous Jadassohn was negative. Due to concerns of possible amblyopia and cosmetics, lamellar keratectomy, sclerotomy, and conjunctivoplasty were performed to remove the epibulbar lesion. The eyelid defect was reconstructed with 6–0 Vicryl sutures. Histopathological examination reported complex choristoma. Upon three-year follow-up, low astigmatism and favorable cosmetics results were achieved. Conclusions Congenital complex choristoma can present clinically as an epibulbar mass with eyelid involvement. The management depends on the extent of involvement, the risk of amblyopia, and cosmetic concerns. The method of eyelid reconstruction should be tailored according to the residual eyelid defect.

Background Acrospiromas are histologically distinct cutaneous tumours of sweat duct origin and usually measure 1 to 2 cm in size. Objective We describe a patient with a large benign eccrine acrospiroma. Methods Case report and literature review. Results A 50-year-old woman underwent excision of a 5.5×5.0 cm cystic mass located on the left gluteal region, and the resulting defect was closed by a local flap. A diagnosis of benign eccrine acrospiroma was made after histopathological examination. On histological examination, the lesion was characterized by multilobular dermal masses composed of a biphasic cell population. There was no recurrence five months after the operation. Conclusion Although eccrine acrospiromas are usually benign, they can, on rare occasions, undergo malignant transformation. In addition, the clinical appearance of this lesion is not specific and differential diagnosis from other lesions, both benign and malignant, can only be done after the complete removal of the lesion.

Background: Langerhans cell histiocytosis (LCH) is a term describing a clonal proliferation of pathologic Langerhans cells (histiocytes), which may manifest as unisystem (unifocal or multifocal) or multisystem disease. LCH is a rare cause of the orbital tumor with the predilection to its lateral wall which is particularly common in children. Case Description: We report an unusual case of a 33-year-old woman, 6 months after childbirth, who presented with the edema of the right orbit and upper eyelid with headaches. On physical examination, the patient had a right superior and lateral swelling of the eyelid and the orbit and right enophthalmos, without blurred vision. Magnetic resonance imaging showed well-defined, expansile, intensely homogeneously enhancing mass lesion in the right superolateral orbital rim with the destruction of the upper wall of the orbit, growing into the frontal sinus and frontal part of the cranium with the bold of the dura mater in this region. Radical excision of the tumor was achieved through a right fronto-temporo-orbito-zygomatic craniotomy. Histopathological examination had confirmed the diagnosis of the LCH. The patient was discharged home with a modified Rankin Scale score of 0. Conclusion: The main purpose of this case report is that LCH should be considered as one of the possible causes of quickly appearing tumor of the orbit in adults.
