Abstract
Localized cutaneous argyria is a rare cutaneous disorder that has been associated with occupational exposure, dental procedures, topical agents, acupuncture, earrings, and nasal piercings. In this paper, we review the current literature on localized cutaneous argyria, highlight its clinical and histologic diagnostic features, and then discuss the clinical and histological differential diagnoses for blue-gray skin and black dermal pigment, respectively. We also discuss the utility of ancillary techniques, such as deeper histologic levels, special stains, darkfield microscopy, and advanced micro-analytical techniques in helping diagnose localized cutaneous argyria. Furthermore, we emphasize that a thorough clinical history and astute clinico-pathologic correlation can be the most important diagnostic techniques in correctly diagnosing this rare disorder. Our review aims serve as a reminder to clinicians and pathologists of the importance of including localized cutaneous argyria in the clinical and histological differential diagnosis of pigmented lesions.

Unsafe Deposits: Overlapping Cutaneous Manifestations of Porphyria Cutanea Tarda, Ochronosis, Hemochromatosis, and Argyria. Skinmed 2019; 17:161-170.

Abstract
Cutaneous deposition disorders represent an array of conditions resulting from the accumulation of endogenous and exogenous substances within the skin. Many of the deposition diseases resemble each other and can also be confused with disorders not related to deposition. Porphyria cutanea tarda (PCT) results from dysfunction particularly in the fifth enzyme of the heme synthesis pathway, leading to increased skin fragility and bullae among other abnormalities. Ochronosis develops from alkaptonuria or exogenous sources, creating deposition of ocher-colored pigment in the skin. Hemochromatosis is a systemic disorder that can be inherited or acquired, altering skin pigmentation in more than 90% of patients. PCT can be an initial manifestation of hemochromatosis. Argyria is an acquired disorder of silver deposition that can also cause pigmentation similar to ochronosis. These uncommon but not rare disorders may resemble and be confused with each other in multiple ways.

Abstract
BackgroundLocalized cutaneous argyria is a rare skin condition caused by direct contact with silver or silver particles. It presents as asymptomatic gray or blue-gray macules that appear similar to blue nevi. Histologic features include brown-colored or black-colored silver granules in the basement membrane and dermis, most commonly surrounding eccrine glands, elastic fibers, and collagen fibrils. The condition is most frequently observed in individuals who are regularly exposed to small silver particles, such as silversmiths and welders. However, localized cutaneous argyria has also been associated with acupuncture needles, silver earrings, and topical medications containing silver nitrate. Although the condition is benign, patients who are concerned about the cosmetic features of localized cutaneous argyria may benefit from laser therapy.PurposeWe describe the clinical and pathologic findings of two women who developed localized cutaneous argyria. We also review the characteristics of other patients with localized cutaneous argyria and summarize the differential diagnosis and treatment options for this condition.Materials and methodsThe features of two women with localized cutaneous argyria are presented. Using PubMed, the following terms were searched and relevant citations assessed: acquired localized argyria, acupuncture, argyria, argyrosis, colloidal silver, cutaneous argyria, and localized cutaneous argyria. In addition, the literature on localized cutaneous argyria is reviewed.ResultsTwo women presented with small, asymptomatic blue-gray macules appearing at sites directly adjacent to ear piercings. A punch biopsy was performed on one woman. Microscopic examination revealed a yellowish-brown colored granular material found adjacent to elastic fibers. Based on correlation of the clinical presentation and histopathologic findings, a diagnosis of localized cutaneous argyria was established. The second woman did not undergo a biopsy. However, the clinical presentation was highly suggestive of localized cutaneous argyria. Both women were reassured of the benign nature of the condition and agreed to return for clinical follow-up if they observed any changes in the appearance of the lesions.

Abstract
Argyria is an uncommon blue-gray pigmentation of the skin (increased in sun-exposed areas), nail unit, and mucous membranes caused by prolonged silver exposure. Commonly occurs in the setting of occupational exposure, silver-containing medications, or systemic absorption from use of silver sulfadiazine on extensive burns/wounds. Recently, there appears to be an increase in the practice of colloidal silver ingestion given the popularity and easy availability of alternative medicines and dietary supplements containing various silver-containing compounds. We report a case of argyria in a 72-year-old male following ingestion of colloidal silver as a supplement for over 10 years. He had a diffuse, blue-gray discoloration of his face and nails. A skin biopsy was performed and histology supported the clinical diagnosis of argyria. Our objective is to increase the awareness for this rare dermatologic entity by highlighting the clinical and histological features through a case report. Dermatologists should warn patients in regards to the use of colloidal silver for alternative health practices.

Abstract
The typical clinical manifestation of localized cutaneous argyria is a blue-grayish asymptomatic macule, which may be caused by occupational exposure, topical treatment, dental amalgams and alternative medicine therapies. The lesions often are clinically indistinguishable from blue nevi and metastatic melanoma. The authors present a case of localized cutaneous argyria secondary to an acupuncture needle, emphasizing the importance of keeping this entity in mind in the differential diagnosis of blue-grayish pigmented lesion in a body area that could have been treated with acupuncture.

Abstract
A 58-year-old woman was referred to our hospital due to progressive skin darkening, which began 5 months previously. The patient had strikingly diffuse blue-gray discoloration of the skin, most prominent in sun-exposed areas, especially her face and hands. The oral mucosa, tongue, gums, eye conjunctiva, ears, nail beds, and trunk were also involved. Bluish-gray discoloration of all nails was aggravated by cold weather. She had ingested 1 L of colloidal silver solution daily for approximately 16 months as a traditional remedy. Her serum silver concentration was 381 ng/ml which was a very high (reference level: <15 ng/ml). Light microscopic examination of a punch biopsy specimen from her nose revealed fine, minute, round, and brown-black granules deposited in the basement membrane of hair follicular epithelium. Scanning electron microscopic examination showed electron-dense granules deposited in the intercellular space of sweat glands. Energy disperse X-ray spectrometry analysis demonstrated peaks for silver and sulfur in the dense black deposits. The ingestion of colloidal silver appears to be an increasing practice among patients using alternative health practices. All silver-containing products including colloidal silver should be labeled with a clear warning to prevent argyria, especially in alternative health practices.

Abstract
Localized cutaneous argyria presenting as an asymptomatic blue-gray macule has been rarely reported from diverse etiologies including occupational exposures, topical medications, alternative medical therapies, body jewelry, and dental procedures (amalgam tattoos). The lesions often are clinically indistinguishable from blue nevi and malignant melanoma. We present a case of localized cutaneous argyria from an acupuncture needle in a patient with a history of malignant melanoma. Fine granules of nonbleachable dark particles coating collagen and elastin fibers, altered yellow-brown collagen bundles similar to ochronosis, and involvement of eccrine structures were histologically consistent with the pseudo-ochronosis pattern of localized cutaneous argyria, demonstrating that clinicopathologic correlation is of crucial importance.

Abstract
BACKGROUND Argyria is often considered an entity of the past, one which has largely disappeared with the cessation of silver usage in oral medications. However, with the practice of colloidal silver ingestion in current "alternative health" treatments, argyria should be considered in the differential diagnosis of blue-gray hyperpigmentation. METHODS A single case report with clinicopathological correlation. RESULTS Histological examination of skin biopsy specimen, which showed perieccrine brown-black granules, verified that colloidal silver rather than a prescribed medication was the source of the patient's dyspigmentation.

Abstract
BACKGROUND Chronic silver intoxication is a rare disease and therefore the typical ocular findings may be missed. Based on a case with severe intoxication, the clinical and histological findings as well as the prognosis in argyria are presented. HISTORY A 33-years-old-employee of a battery production plant developed a biopsy proven systemic argyria. On slit lamp examination the conjunctiva showed a dark, blue-grey discoloration in the areas of the tear flow and the small conjunctival arteries. Diffuse silver deposits were noticed on the level of Descemet's membrane without endothelial damage. Silver deposits were also visible in the trabecular meshwork. Chemical reaction of the silver particles upon exposure to UV light results in irreversible tissue discoloration. Without options for an effective treatment, early diagnosis and prevention of overexposure are most important. CONCLUSIONS The typical ocular findings in systemic argyria are helpful in occupational medicine for establishing the correct diagnosis.

Abstract
The authors, basing on three cases published by different authors in the years 1995-2003, discuss the problem of diagnosis and treatment of local gingival argyrosis and amalgam tattoo. Treatment methods carried out consisted of the following procedures free gingival graft, subepithelial connective tissue graft in a two-step procedure and subepithelial connective tissue graft without flap coverage. In the authors opinion in some cases a connective tissue graft does not need flap coverage, therefore a dual blood supply is not necessary.

Abstract
PURPOSE To report cases of ocular argyrosis that developed after long-term self-application of commercially available eyelash tint. DESIGN Observational case series. METHODS Case review, clinicopathologic analysis, and literature review. RESULTS Three patients developed ocular argyrosis after the long-term self-application of Revlon Professional Roux Lash and Brow Tint (Colomer USA Corp, New York, New York, USA). Clinical evaluation revealed various degrees of silver deposition on the upper eyelid, lid margin, caruncle and conjunctiva, and diffuse Descemet's membrane deposits. In one case, histologic examination demonstrated silver deposition in the basement membrane and superficial substantia propria of the conjunctiva. CONCLUSIONS Argyrosis can occur after long-term application of readily available eyelash tints, and the deposition of silver may be permanent. In certain circumstances, conjunctival argyrosis may simulate benign and malignant lesions, including conjunctival melanoma. These products should only be applied by trained cosmetologists.

Abstract
We experienced a case of membranous nephropathy associated with argyria. The patient was a 78-year-old woman who had noticed blue skin of the face and azure lunulae for 8 years. She was admitted to our hospital for edema and proteinuria. She was diagnosed as membranous nephropathy by needle renal biopsy, and treated with prednisolone. Her proteinuria disappeared after 63 days. We investigated the blue skin of her face and azure lunulae. Skin biopsy was performed and black granules deposited in the upper layer of the corium were observed. The granules were identified with silver by EDS (energy-dispersive X-ray spectroscopy) analysis. Membranous nephropathy associated with gold or mercury has been reported, but association with silver has not been reported. We considered that this is a rare case of membranous nephropathy associated with silver.

Amalgam tattoo (amalgam pigmentation) of the oral mucosa: clinical manifestations, diagnosis and treatment. REFU'AT HA-PEH VEHA-SHINAYIM (1993) 2004; 21:25-8, 92.

Abstract
Amalgam tattoo is an iatrogenic lesion caused by traumatic implantation of dental amalgam into soft tissue. Amalgam tattoo is the most common localized pigmented lesion in the mouth. In a study of a mass screening oral examination in the United States, it was found in about 0.4-0.9% of the adult population and in Sweden in about 8%. Clinically, amalgam tattoo presents as a dark gray or blue, flat macule located adjacent to a restored tooth. Most are located on the gingiva and alveolar mucosa followed by the buccal mucosa and the floor of the mouth. Microscopic examination reveals that amalgam is present in the tissues in two forms: as irregular dark, solid fragments of metal or as numerous, discrete fine, brown or black granules dispersed along collagen bundles and around small blood vessels and nerves. In most lesions, it is presented in both forms. The biologic response to the amalgam is related to particle size, quantity and elemental composition of the amalgam. Large fragments often become surrounded by dense fibrous connective tissue. Smaller particles are associated with mild to moderate chronic inflammatory response with individual macrophages engulfing small amalgam particles. Occasionally, the reaction takes the form of foreign body granuloma in which macrophages and multinucleated giant cells are present. Some of the multinucleated giant cells also contain amalgam particles. Diagnosis of amalgam tattoo is usually obvious from the location and clinical appearance. A radiograph is recommended to confirm the presence of metallic particles, but absence of radiographic evidence does not rule out the possibility, since particles are often too fine or widely dispersed to be visible on radiographs. When there is no radiographic evidence or an adjacent restored tooth, biopsy is recommended to rule out an early melanoma. Once the diagnosis of amalgam tattoo has been established, no additional treatment is necessary except for cosmetic reasons. If the pigmentation is cosmetically unacceptable, surgical excision and transplantation of oral mucosal tissue has been suggested. Q-switched ruby laser and Q-switched alexandrite laser have also been used with favorable results.

Abstract
PURPOSE To determine the value of confocal and specular microscopy in the examination of corneal argyrosis in art silver solderers. METHODS Six patients with corneal argyrosis underwent a complete physical and ophthalmologic examination. Specular microscopy was performed in three cases, and in vivo confocal microscopy in four cases. Ultrasound biomicroscopy and corneal topography were performed in three cases. A conjunctival specimen of one patient was examined histologically in paraffin sections. RESULTS Slit-lamp examination showed gray, diffuse opacities in the deep corneal stroma. Confocal microscopy showed highly reflective deposits with a granular pattern anterior to the corneal endothelium and hypereflective keratocyte nuclei with visible cytoplasm in the anterior stroma. Specular microscopy demonstrated round white bodies anterior to the corneal endothelium. Silver deposits were not found histologically. CONCLUSIONS Silver solderers with long-term exposure to silver compounds are at high risk of developing corneal argyrosis. We conclude that specular microscopy and in vivo confocal microscopy provided important information for the diagnosis of corneal argyrosis.

Abstract
Argyria is a rare cause of cutaneous discolouration caused by silver deposition. We report a case of dramatic and diffuse argyria secondary to ingestion of colloidal silver protein over a 1-year period. Stained electron microscopy with spectral analysis was used to confirm the clinical diagnosis. Silver-protein complexes are deposited in the skin and reduced to inert silver salts by sunlight in a process similar to that harnessed in photography. Our patient had obtained the silver for consumption via mail order. It had been advertised as a cure for a variety of diseases. Colloidal silver protein is commercially available as a 'food supplement', hence circumventing the strict controls placed on medicines.

Abstract
We report a 66-year-old woman with localized argyria caused by embedding of acupuncture needles. Ten years after she had received acupuncture, she noticed two asymptomatic bluish macules on her right arm. A biopsied specimen from the macule revealed many brownish-black granules mainly located around the sweat glands and the blood vessels in the dermis. The X-ray examination of the extremities revealed numerous needle-like fragments around her extremities. "Embedding of needles" induces some serious adverse events. We should know the adverse events for the safety and health of patients.

Abstract
BACKGROUND Localized argyria is uncommon and presents clinically as asymptomatic slate gray macules or blue macules resembling blue nevi. Its histopathologic features are usually similar to those of generalized argyria in which silver granules are found most commonly around the eccrine glands, in the walls of blood vessels, and along elastic fibers. Ochre swollen homogenized collagen bundles resembling ochronosis have not been previously described. OBJECTIVE The purpose of this study is to report a series of 5 patients with localized argyria with the histologic feature of "pseudo-ochronosis." In one patient, biopsy was performed on 2 distinct lesions. METHODS All patients underwent skin biopsies for light microscopy and darkfield microscopy. In two patients, the biopsy specimens were analyzed with a mass spectrophotometer; scanning electron microscopy and energy-dispersive x-ray analysis were performed. In one patient, the biopsy specimen was decolorized with 1% potassium ferricyanide in 20% sodium thiosulfate. RESULTS All 5 patients presented with the typical clinical and histologic features of localized argyria. Ochre swollen and homogenized collagen bundles were seen in all cases. In addition, light microscopy in 4 cases revealed an ellipsoid black globule within a zone of collagen degeneration. CONCLUSION The histologic features of localized argyria include swollen and homogenized collagen bundles resembling ochronosis, "pseudo-ochronosis," which may be more common than previously recognized.

Abstract
PURPOSE To document the clinical and histopathologic corneal features of a patient who developed multifocal corneal argyrosis after a chemical explosion injury with unusual involvement of the corneal stroma and keratocytes. METHODS The corneal button was investigated by light and transmission electron microscopy and scanning electron microscopy combined with energy-dispersive x-ray microanalysis. RESULTS Clinically, the patient showed dark discoloration of the lids, periocular skin, episclera, and conjunctiva and had multiple brown dots in the superficial layers of the cornea. Microscopic examination of the cornea showed diffuse deposition of silver particles in the epithelial basement membrane, Bowman's layer, and Descemet's membrane. In the corneal stroma, silver granules accumulated intracellularly within lysosomal structures of degenerative keratocytes and extracellularly in association with collagen fibers and cellular debris. Energy-dispersive x-ray analysis showed peaks of silver and sulfur. CONCLUSION The toxic influence of intracellular accumulation of silver in stromal keratocytes may lead to cell damage and necrosis and result in visual impairment.

Abstract
Silver can be absorbed through ingestion, topical administration, or inhalation. Generalized argyria results from deposition of silver in the skin, nails, mucous membranes, and internal organs and is characterized by a diffuse bluish-gray discoloration in sun-exposed areas. We report two cases of generalized argyria in patients on maintenance hemodialysis (HD) therapy for more than 15 years. They presented with diffuse hyperpigmentation of the face that was mistaken to be related to uremia and bluish-gray discoloration of all nails believed to be cyanosis. Histopathologic examination of skin biopsy specimens showed characteristic findings of argyria, which was further confirmed by radiograph microanalysis. Their serum silver levels were also elevated. No definite silver source could be determined. However, their argyria might be related to their long-term HD therapy because (1) they had been on HD therapy for more than 15 years and the discoloration appeared several years afterward, and (2) the water used for HD was not well processed in the early 1980s in TAIWAN: Argyria should be suspected in chronic HD patients presenting with a diffuse bluish-gray discoloration of the skin and nails and evaluated carefully by skin biopsy.

Abstract
BACKGROUND A pigmented episcleral lesion may have several etiologies. We describe the rare occurrence of a localized argyrosis secondary to former strabismus treatment. HISTORY A 70-year old female patient was referred to our clinic for diagnosis and treatment of a pigmented episcleral process near the insertion of the left lateral rectus muscle which was noticed on a routine control by her ophthalmologist. The patient was free from ocular symptoms. There was a history of strabismus surgery on the left eye at the age of twelve. Due to the suspicious appearance of the lesion the possibility of a conjunctival malignant melanoma was considered. A ultrasound exam could not exclude this suspicion and therefore a biopsy was performed. Silver deposits and rests of a suture could be found. CONCLUSION Silver deposits are a rare cause of a pigmented localized episcleral lesion. Several possibilities of silver contamination in our patient are discussed. The most likely explanation is the use of silver containing suture material in strabismus surgery performed 58 years ago. A localized argyrosis secondary to past strabismus surgery should therefore be included in the differential diagnosis of a pigmented episcleral lesion.

Abstract
24 cases of amalgam pigmentation were analyzed by light microscope. 16 cases were amalgam debris, 8 cases were amalgam fragments and debris mixed. The amalgam distributed mainly along basement membrane of the epithelium, wall of blood vessels, nerve fibers, reticular fibers and endomysiums. In case where amalgam entered the bone, bone cells disappeared, lacuna emptied and microfracture of bony trabecullae occurred. In 8 cases pathologic calcification were found and in 18 cases there were inflammatory responses. 2 cases were analyzed by energy dispersive X-ray. It was found that in the different sites of tissues there were different content of Ag, Hg, Sn and Ca.

Abstract
A 74 year old man presented with signs and symptoms of mild cardiac failure. His face and chest were severely discoloured, which was thought to be due to cyanosis. He deteriorated and died of bronchopneumonia. At post mortem examination multiple organs, including the skin, showed silver pigment deposition; he also had a gastric malignant neuroendocrine tumour. He gave no history of contact with silver compounds. Systemic argyria caused by chronic ingestion of silver compounds is a rare condition which, apart from its cosmetic effects, is thought to be relatively harmless; it is not thought to be carcinogenic. This condition can pose diagnostic problems for both clinicians and pathologists.

Abstract
Generalized argyria, the systemic dissemination and tissue deposition of silver-containing particles, is characterized by slate gray discoloration of skin, most pronounced in sun exposed areas. A 33-year-old woman visited our dermatologic clinic complaining of frequent oral ulceration for 10 years and generalized discoloration of her skin for 5 years. She had had her tongue painted with silver nitrate repeatedly 6 years ago for the treatment of oral ulcers. Physical examination showed slate gray discoloration of her skin, most pronounced on the face and neck. The oral mucosa, tongue, sclera, and conjunctiva also had a slightly blue-gray discoloration. Biopsy specimens from the oral mucosa and forearm revealed small brown-black granules scattered in the dermis and basal lamina of eccrine sweat glands, blood vessels, and hair follicles under the light microscope. Tiny black granules were most numerous in the basal laminae of vessels in electron microscopic observation. Energy dispersive X-ray microanalysis (EDXA) confirmed that many of the granules contained silver.

Abstract
A case of localized argyria with chrysiasis caused by implanted acupuncture needles in a 41-year-old Japanese woman was studied by electron microscopy and x-ray microanalysis. Large amounts of silver granules with selenium and sulfur were detected around eccrine secretory cells in much greater amounts than around ductal cells. Many granules were also observed along the outer edge of the basement membrane but never within cells or intercellular spaces. The granules were also present around blood vessels, lymphatics and nerve fibers, and in elastic fibers. Small numbers of gold fragments were also seen, mostly within macrophages. These results suggest that silver deposits extracellularly as selenide and sulfide, whereas free gold is found intracellularly.

Abstract
A 69-year-old woman was referred to our hospital for evaluation of pyuria and renal dysfunction. Twenty days earlier, the patient had undergone silver nitrate retrograde instillations for essential renal bleeding. Routine laboratory findings showed renal dysfunction with a serum creatinine concentration of 7.2 mg/dl and blood urea nitrogen concentration of 68 mg/dl. The urine contained numerous red cells and white cells. The plain X-ray film of the abdomen revealed right renal calcification. Computed tomographic scan confirmed the calcifications in the right renal collecting systems and parenchyma. The most likely diagnosis was argyrosis of the upper urinary tract. The patient underwent a right nephrectomy. Histopathological examination of the specimen showed that the renal pelvis was filled with blood clots. Laboratory evaluation including serum creatinine concentration and urinalysis revealed normal parameters postoperatively. We conclude that this patient developed argyrosis of the urinary tract, and review previously published papers concerning complications of silver nitrate instillation.
