Molluscum contagiosum is a benign viral cutaneous infection. It typically presents as an asymptomatic centrally umbilicated nodule 3–5 mm in diameter. Susceptible patients are children and adults receiving immunosuppressive therapy. We report a case of an eyelid molluscum contagiosum in a 5-year-old boy with no risk factors and a 2-week history of a large localized ulcerating mass of the left upper eyelid. The mass was totally excised, and diagnosis of molluscum contagiosum was confirmed in the histopathology study. Microscopic examination revealed enlarged keratinocytes, and acquired eosinophilic Henderson-Patterson inclusion bodies were also detected. Such ulcerating solitary lesions can be misdiagnosed as infected epidermal cysts, keratoacanthoma, or infected chalazions; therefore, molluscum contagiosum should be considered in the differential diagnosis. Complete excisional biopsy of the mass is diagnostic and curative.
Introduction and importance
Pilomatrixoma is a superficial benign skin tumor that originates from the matrix cells of the hair follicles. It presents more frequently during the first two decades of life and usually involves the head and neck, most often in the eyelid or eyebrow area.
Case presentation
We present a case of pilomatrixoma, which appeared at the age of 14 years with history of recurrent inflammation and discharge mimicking a ruptured epidermal cyst.
Discussion
Pilomatrixomas are often confused clinically with other benign masses, encountered in the clinical practice more frequently like dermoid cysts and epidermal inclusion cysts. The rate of accurate preoperative diagnosis ranges between 0%–30% and the correct diagnosis can be established only after excision and histopathological examination. Our case demonstrates an atypical presentation of pilomatrixoma as an epidermal inclusion cyst.
Conclusion
Ophthalmologists and ocular pathologists should be aware of the atypical presentation of pilomatrixomas to ensure early accurate diagnosis and curative treatment.
Purpose
Self-medication is the selection and use of drugs by individuals to treat self-diagnosed diseases or symptoms. While some patients regard self-medicating as harmless, it is far from being a safe practice. The aim of this study was to evaluate the knowledge, attitudes, and practices toward self-medicating eye symptoms in Saudi Arabia.
Patients and Methods
A cross-sectional study was conducted through an online questionnaire on a study population that consisted of Saudi nationals aged 18 and older who were using or had previously used ophthalmic medications.
Results
Among the 524 responses obtained, 79.4% were female, and more than half were less than 40 years old. Participants admitting to practicing ophthalmic self-medication measured 62.4%. The most commonly self-prescribed ophthalmic medications were artificial tears (n=276), followed by antiallergic (n=57) and antibiotic medications (n=33). Many participants reported that the reason for self-treatment was for repeated and simple symptoms that did not require professional care. While approximately 51% showed high levels of knowledge about ophthalmic medications, no significant relationship was seen with their choice to self-medicate (P=0.153).
Conclusion
Despite detecting a high level of knowledge and acceptable practices and attitudes among participants, a high incidence of self-medication was observed. This effect was mostly attributed to long hospital waiting times and patient self-diagnosis. Increasing the number of healthcare units and properly educating patients on ophthalmic medications may help decrease the incidence of self-medication.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
