| Abstract|| |
Lipoid proteinosis is a very rare, autosomal recessive disorder, characterized by hoarseness of voice, skin scarring, beaded papules along the eyelid margins, and an inability to protrude the enlarged tongue. Infiltration of hyaline material to various organs is found to be responsible for the various manifestations of this disorder. It is mainly prevalent in early infancy and childhood, and is rare in older adults. In this article, we report a 61-year-old patient with the skin and orofacial features of lipoid proteinosis, which is very rarely recorded in literature as far as age and oral manifestation are concerned.

| Introduction|| |
Lipoid proteinosis (LiP) was first reported by Seibman in 1908.  In 1929, Urbach and Wiethe described an entity called " lipoidosis cutis et mucosae" on the basis of deposition of a lipid material associated with protein around the blood vessels in the skin and mucus membrane, and this name was then changed to "lipoid proteinosis."  LiP is a rare autosomal recessive hereditary disorder, characterized by hoarseness of voice with skin and mucosal changes. Previous studies have attributed the prevalence of LiP to consanguineous parents and infancy. Here, we report a case of LiP in a 61-year-older patient with oral manifestations but without a history of consanguinity. Also, interestingly, the patient was suffering from this manifestation for the past 6 months only, which is a very rare occurrence with respect to age.
| Case Report|| |
A 61-year-old male patient was referred to our department for evaluation of stiffness of his tongue, slurred speech, and hoarseness of voice for the past 6 months. Patient developed hoarseness of voice 6 months before, which was followed by slurred speech and dysphagia to solid food insidiously. Before developing these symptoms, he was apparently normal; even during infancy and adulthood, no significant complaints were reported. Family history and personal history was non-contributory. None of the family members were affected and no history of consanguinity was recorded. Patient was otherwise apparently healthy; no significant systemic illness was noted. No history of seizures, visual disturbances, photosensitivity, or respiratory obstruction were reported. Skin of face and neck showed multiple acneiform scars [Figure 1]a and b and beaded papules along the margins of the eyelids [Figure 2]. Intraorally, the tongue was firm, enlarged, crenated, with yellowish white papule on its surface [Figure 3]. The tongue movements were restricted due to infiltration of the yellowish papule in frenulum region. Oral mucosa showed generalized thickening with yellowish papular infiltration. The yellowish papule was widespread throughout the oral mucosa including buccal mucosa and labial mucosa [Figure 4]. No abnormality was noted in the dentition and it was found to be normal for this age. Xerostomia and dysphagia were also found to be present on detailed evaluation. Routine hemogram, renal and liver function tests were normal. Radiographic examination of the skull was found to be unremarkable, with no evidence of calcification noted. Endoscopy was also performed, but no significant abnormality was detected. MRI of brain was taken to rule out any neurological abnormality; no relevant positive findings were noted. Based on the clinical evidence, the case was provisionally diagnosed as LiP and possible differential diagnoses of amyloidosis, xanthoma, porphyria, and myxedema were also given. Incisional biopsy was carried out in the lower labial mucosal region and histopathologic examination showed fibrous tissue with focal areas of hyaline amorphous eosinophilic material deposits [Figure 5]a. Periodic acid-Schiff (PAS) test was positive around the blood vessel [Figure 5]b. These findings confirmed the diagnosis of LiP. Patient was then referred to gastroenterologist for opinion regarding dysphagia and hoarseness of voice. Oral prophylaxis was carried out and the patient was then advised D-pencillamine 600 mg/day for 6 months, which resulted in improvement in oral symptoms. Patient is under regular follow-up; no significant adverse effect has been noticed till date.

| Discussion|| |
LiP, also called as Urbach-Wiethe disease, is characterized by the widespread deposition of hyaline material, particularly in the skin and mucus membranes of the mouth, pharynx, and larynx. This disorder is more prevalent in early infancy with hoarseness of voice, pox-like and acneiform scars.  Mutations in gene encoding a glycoprotein, extracellular matrix protein (ECM1), that is expressed in several tissues, are responsible for deposition of hyaline material in dermis and thickening of the skin, mucus and basement membrane around the blood vessels and adnexal epithelia.  This glycoprotein is composed of two isoforms, ECM1a and ECM1b, among which ECM1b lacks exon 7 of the 10-exon gene. Exons 6 and 7 are the most common sites for ECM1 mutations in LiP. Normal binding to type IV collagen is also disturbed due to this mutation, resulting in increased type V collagen expression and typical histopathological changes. Mutations in gene encoding ECM1 on chromosome 1q21 have been identified in most cases of LiP reported in literature.  The manifestations of LiP are associated with extensive deposition of non-collagenous proteins and glycoproteins in the skin, mucosa, and other organs. The disease is also postulated to be the result of multiple enzymatic defects, similar to lysosomal storage disorders. 
Initial manifestation usually appears in infancy as a weak cry and hoarseness of voice. Cutaneous lesions may not occur until 10 years of age, making the diagnosis in children difficult. Skin lesions are more prominent on sun-exposed areas, especially on face and chest. Diffusely thickened facial skin usually has a waxy texture and is covered with widespread infiltrated yellowish flat papules, and plaques with acneiform scars. , Beaded papules along the eyelid margins, resembling a string of pearls, termed "moniliform blepharosis," is a pathognomonic sign of this disorder and was observed in our case.  Hoarseness of voice, dysphagia, and altered speech are some of the common initial symptoms and LiP should be considered as provisional diagnosis when these symptoms are reported. Oral mucosa is invariably the initial affected site. Due to infiltration of hyaline material in the frenum, restricted tongue movement can occur and infection of airway leads to respiratory distress.  Xerostomia is one of the common manifestations caused due to widespread infiltration in the oral mucosa. Areas like palms, axillae, knee, and elbows which are subjected to constant mechanical trauma may develop a hyperkeratotic, verrucous surface. Central nervous system can be involved in the form of calcified spots in the temporal lobes or hippocampus amygdale, which may manifest as seizures.  But in our patient, MRI study was normal and no significant abnormalities were detected. Correlation between seizures and intracranial calcifications, which are reported in about 25% of LiP patients, is not established.
LiP must be differentiated from erythropoietic protoporphyria, a condition characterized by skin involvement confined to sun-exposed areas and associated with photosensitivity. Oral manifestation is very rare in this occurrence. Clinical diagnosis is confirmed by histopathological examination. Histologic H and E stained sections show the presence of amorphous, extracellular, and eosinophilic hyaline material. They are PAS positive and diastase resistant.  LiP should also be histologically differentiated from amyloidosis and xanthomas, which are also closely associated with the deposition of storage material in the skin and mucosa.  Due to rarity of the condition, there are no large case series to evaluate the therapeutic options. Despite many therapeutic trials for LiP, treatment of this condition remains unsatisfactory and mainly aims at reducing morbidity and preventing complications. Medical treatments including d-penicillamine, oral steroids, dimethyl sulfoxide, acitretin, and etretinate have been tried. , Among these, d-penicillamine has shown reasonably good results. For our patient, D-penicillamine was used as it has the properties of impairing fibroblast proliferation and cross-linking of collagen. Surgical care involves resection of the vocal cord papules to improve vocal quality. The prognosis of LiP is generally good, although the disease is progressive until early adult life. A dental surgeon is often in the earliest position to diagnose LiP and refer the patient to a specialist, thereby reducing the morbidity of the patient.
