Intratarsal Keratinous Cyst Clinically Misdiagnosed as a Chalazion.

The intratarsal keratinous cyst (IKC) is a recently described entity, often clinically misdiagnosed as a chalazion. We report a case of a 61-year-old male patient with a chief complaint of a small lesion on the upper eyelid that evolved over six months. On physical examination, an asymptomatic, firm nodule was identified on the left upper eyelid. The patient reported no history of trauma. A provisional diagnosis of chalazion was established, and an excisional biopsy was performed. Histopathologically, the lesion was lined with a stratified squamous epithelium, with a corrugated epithelial surface showing abrupt keratinization without keratohyalin granules, and compact keratinous-appearing material in the cystic lumen. The diagnosis was IKC. No signs of recurrence were observed after one year of follow-up. It is essential to accurately diagnose IKC and distinguish it from chalazion and epidermal inclusion cysts, because IKC requires complete surgical excision and can exhibit multiple recurrences if not properly removed.

Idiopathic aseptic facial granuloma: A retrospective study of 43 cases.

BACKGROUND: Idiopathic aseptic facial granuloma (IAFG) is an underrecognized pediatric skin disease, currently considered within the spectrum of rosacea. It usually manifests as a solitary, reddish, asymptomatic nodule on the cheek that resolves spontaneously. METHODS: Retrospective and descriptive observational study of 43 pediatric patients with a clinical diagnosis of IAFG, followed between 2004 and 2022, at two general hospitals in Argentina. RESULTS: IAFG predominated in girls (65%) and the average age of onset was about 6 years. A single asymptomatic nodule was seen in 79% of patients. The most common localization was the cheek (58%) followed by lower eyelids (41%). Family history of rosacea was present in 16% of patients. A concomitant diagnosis of rosacea and periorificial dermatitis was made in 14% and 9% of our population, respectively. Past or present history of chalazia was detected in 42% of the children. IAFG diagnosis was mainly clinical (88% of cases). Oral antibiotics were the most common indicated treatment (84%). Complete healing was achieved by the majority, but 18% of those with eyelid compromise healed with scars. CONCLUSIONS: IAFG is a benign pediatric condition that physicians should recognize in order to manage correctly. We herein refer to a particular morphologic aspect of IAFG lesions affecting the lower eyelids, where nodules adopt a linear distribution and have a higher probability of involute leaving a scar. Also, we consider that the concomitant findings of rosacea, periorificial dermatitis and chalazia in our patients, reinforce the consideration of IAFG within the spectrum of rosacea.

Background: There has been increasing interest in Demodex and its association with conditions such as rosacea, blepharitis, chalazion, meibomitis and keratoconjunctivitis; and ivermectin as a treatment has been reported both in dermatology and ophthalmology. Objective: To review the literature in order to determine the role of Demodex in ocular surface inflammation and the use of ivermectin for its treatment. Study design: Review of the literature. Methods: An article search was done in PubMed with the following terms: Demodex, ocular rosacea, chalazion, pediatric rosacea, meibomitis, keratoconjunctivitis and ivermectin. Results: A review including the epidemiology and pathophysiology of ocular inflammation associated with Demodex is presented. Current knowledge on Demodex and rosacea, chalazion, blepharitis, meibomitis, keratoconjunctivitis and ocular rosacea is summarized. Relevant articles on the use of ivermectin for these conditions are listed. Conclusions: Recent evidence suggests Demodex is a trigger for a number of ocular surface inflammatory conditions. Although more studies are necessary to determine the effectiveness of topical ivermectin, current knowledge supports its acaricidal action against Demodex

A Case of Recurrent Chalazia Associated with Subclinical Hypothyroidism.

Chalazia are chronic inflammatory disorders of the Meibomian glands of the eyelids that can present at any age. Although the exact cause is still obscure, they are often associated with retention of lipids in these sebaceous glands, infections, or disturbances in the balance of sex hormones. The complications of the disease may vary from little discomfort to reduced vision. Treatment strategies include hot compresses, intralesional steroid injections, and incision and curettage. The present case is about a female in her forties with a 4-year long history of recurrent chalazia. The management of the majority of the lesions was through incision and curettage. Concomitantly she presented with subclinical hypothyroidism, for which she received treatment. During treatment of the hypothyroidism, there was a remission of the chalazia. After cessation of the treatment with levothyroxine, the chalazia started recurring. Reinstatement of a low-dose treatment with levothyroxine eventually led to a remission and prevented further recurrence of the chalazia. Subclinical hypothyroidism may predispose to recurrent chalazia. This finding may have consequences for the understanding of the pathophysiology and the management of this disorder. Further investigations must elicit the exact mechanism of this association.

Ocular demodicosis: A review. / Demodicosis ocular: una revisión.

Demodex folliculorum and Demodex brevis are ectoparasites that inhabit the skin of humans. They have been related to alterations in the ocular surface, such as, dysfunction of Meibomian glands, blepharitis, chalazion, etc. Ocular demodicosis is characterised by the pathognomonic presence of cylindrical dandruff at the base of the eyelashes, and various symptoms including, among others, itching, lacrimation, and hyperaemia. A bibliographic review was carried out on the role of Demodex spp. in ocular disease, including publications made by the scientific society between 2005 and 2018. A significant relationship was found between prevalence and incidence of Demodex spp. in eye diseases. D. folliculorum is usually found more frequently than D. brevis in ocular infestation, with the prevalence or incidence of infestation by both species increasing with the age of the patient. In patients with blepharitis or other infectious diseases of the ocular surface, unresolved with antibacterial treatment, the search for Demodex spp. should be considered.

Primary cutaneous adenoid cystic carcinoma of the eyelid and literature review / Carcinoma adenóide cístico cutâneo primário de pálpebra e revisão da literatura

ABSTRACTPrimary cutaneous adenoid cystic carcinoma (PCACC) is a rare malignant epithelial tumor most commonly observed in the scalp and skin of the chest and originating from the palpebral portion of the lacrimal gland in the orbit. Here we describe the diagnosis and treatment of a rare case of PCACC in an eye of a 52-year-old male. The patient presented with a mass lesion of the right lower eyelid. During incisional biopsy, lack of encapsulation and a secretion pattern different to that of chalazion was observed, which differentiated the lesion from chalazion. Pathological analysis revealed the diagnosis of PCACC. This case highlights the importance of careful inspection for macroscopic differentiation of PCACC from chalazion after initial surgery and pathological evaluation of all surgically removed mass lesions for accurate diagnosis and treatment.

RESUMOO carcinoma adenóide cístico cutâneo primário (PCACC) é um tumor maligno epitelial raro, mais comumente observado no couro cabeludo e na pele do peito sendo originário da porção palpebral da glândula lacrimal na órbita. Apresentamos o diagnóstico e tratamento de um caso raro de carcinoma adenóide cístico cutâneo primário do olho em um paciente do sexo masculino de 52 anos de idade, com uma lesão maciça da pálpebra inferior direita. A observação da falta de encapsulamento e um padrão de secreção diferente do calázio durante biópsia incisional permitiu a diferenciação da lesão de um calázio. A avaliação dos resultados do exame patológico resultou no diagnóstico de carcinoma adenóide cístico cutâneo primário. A análise do caso indica a importância de uma inspeção cuidadosa para a diferenciação macroscópica da carcinoma adenóide cístico cutâneo primário do calázio após a cirurgia inicial e avaliação patológica de todas as lesões de massa removidas cirurgicamente para o diagnóstico e tratamento corretos.

Calázio e características demográficas dos portadores em uma amostra populacional / Chalazion and demographic characteristics of patients in a population sample

Objetivo: Apresentar a frequência de ocorrência do calázio em uma amostra populacional, assim como as características de seus portadores. Métodos: Estudo transversal utilizando amostra populacional aleatorizada, realizado nos anos 2004/2005, na região centro-oeste do estado de São Paulo. Os participantes foram avaliados segundo variáveis demográficas e exame oftalmológico. Resultados: A frequência de ocorrência do calázio foi de 1,56%, sendo mais frequente em mulheres, portadores de astigmatismo ou hipermetropia de pequenos graus, com grande variação de idade de acometimento. Foi necessária prescrição de correção óptica e cirurgia em número expressivo de casos. Conclusão: O calázio tem baixa frequência de ocorrência na população geral. Ocorre predominantemente em mulheres e há associação importante com ametropia.

Purpose: To show the frequency of occurrence of chalazion in a population sample, as well as the characteristics of patients. Methods: A cross-sectional study using randomized population sample was carried out during 2004/2005, in the Midwest region of the state of São Paulo. Participants were evaluated according to demographic variables and ocular examination. Results: The frequency of occurrence of chalazion was 1.56‰, more common in women, people with astigmatism or low hyperopia, with wide variation in age of onset. It was necessary to prescribe optical correction and surgery in a significant number of cases. Conclusion: The chalazion has low frequency of occurrence in the general population. It occurs predominantly in women and there is a significant association with refractive error.

Uso da pinça de calázio para biópsia de glândula salivar menor no diagnóstico da síndrome de Sjögren / Use of chalazion clamp for minor salivary gland biopsy in the diagnosis of Sjögren's syndrome

A biópsia da glândula salivar menor é essencial para o diagnóstico da síndrome de Sjögren. Os autores demonstram o uso da pinça de calázio para facilitar este procedimento. A pinça de calázio retém o sangramento da mucosa labial e expõe mais facilmente as glândulas salivares para a sua dissecação e exérese individual, o que facilita a remoção de várias glândulas para a realização do exame histopatológico.

Minor salivary gland biopsy is essential for the diagnosis of Sjögren's syndrome. The authors demonstrate the use of chalazion clamp to facilitate this procedure. Chalazion clamp retains the lip mucosal bleeding and exposes the salivary glands more easily for their dissection and excision individually, which facilitates the removal of various glands to histopathological examination.
