Abstract
BACKGROUND Autoimmune Polyglandular Syndrome type 1 (APS-1) is a rare recessive inherited disease, caused by AutoImmune Regulator (AIRE) gene mutations and characterized by three major manifestations: chronic mucocutaneous candidiasis (CMC), chronic hypoparathyroidism (CH) and Addison's disease (AD). METHODS Autoimmune conditions and associated autoantibodies (Abs) were analyzed in 158 Italian patients (103 females and 55 males; F/M 1.9/1) at the onset and during a follow-up of 23.7 ± 15.1 years. AIRE mutations were determined. RESULTS The prevalence of APS-1 was 2.6 cases/million (range 0.5-17 in different regions). At the onset 93% of patients presented with one or more components of the classical triad and 7% with other components. At the end of follow-up, 86.1% had CH, 77.2% AD, 74.7% CMC, 49.5% premature menopause, 29.7% autoimmune intestinal dysfunction, 27.8% autoimmune thyroid diseases, 25.9% autoimmune gastritis/pernicious anemia, 25.3% ectodermal dystrophy, 24% alopecia, 21.5% autoimmune hepatitis, 17% vitiligo, 13.3% cholelithiasis, 5.7% connective diseases, 4.4% asplenia, 2.5% celiac disease and 13.9% cancer. Overall, 991 diseases (6.3 diseases/patient) were found. Interferon-ω Abs (IFNωAbs) were positive in 91.1% of patients. Overall mortality was 14.6%. The AIRE mutation R139X was found in 21.3% of tested alleles, R257X in 11.8%, W78R in 11.4%, C322fsX372 in 8.8%, T16M in 6.2%, R203X in 4%, and A21V in 2.9%. Less frequent mutations were present in 12.9%, very rare in 9.6% while no mutations in 11% of the cases. CONCLUSIONS In Italy, APS-1 is a rare disorder presenting with the three major manifestations and associated with different AIRE gene mutations. IFNωAbs are markers of APS-1 and other organ-specific autoantibodies are markers of clinical, subclinical or potential autoimmune conditions.

Autoimmune polyendocrine syndrome type 1 (APECED) in the Indian population: case report and review of a series of 45 patients. J Endocrinol Invest 2021; 44:661-677.

Abstract
BACKGROUND Autoimmune polyendocrinopathy-candidiasis-ectodermal-dystrophy (APECED) or autoimmune polyglandular syndrome type 1 (APS-1) is a rare autosomal recessive genetic disease due to mutations in the AIRE (AutoImmune REgulator) gene. The clinical diagnosis is classically based on the presence of at least two of the three main components: chronic mucocutaneous candidiasis, hypoparathyroidism and primary adrenal insufficiency. Patients often suffer from other endocrine or non-endocrine autoimmune conditions throughout life. APECED etiopathogenesis is mediated by T lymphocytes. Autoantibodies against proteins of the affected organs are found in the serum of APECED patients as well as neutralizing antibodies against cytokines. We report here the clinical and genetic characteristics of 45 Indian APECED patients in comparison to Finnish, Sardinian, Turkish and North/South American cohorts from their published results. We also report a new case of APECED of Indian origin, a 2-year old child suffering from chronic mucocutaneous candidiasis since the age of 8 months, with confirmatory AIRE homozygous mutation c.274C > T (p.R92W). CONCLUSION With the inherent limitations of a retrospective study, analysis of Indian APECED patients suggested that compared to classic criteria, application of Ferre/Lionakis criteria validated in North/South American patients could help in earlier diagnosis in 3 of 8 (37.5%) patients for whom adequate information for evaluation was available.

Human STAT1 Gain-of-Function Heterozygous Mutations: Chronic Mucocutaneous Candidiasis and Type I Interferonopathy. J Clin Immunol 2020; 40:1065-1081.

Abstract
Heterozygous gain-of-function (GOF) mutations in STAT1 in patients with chronic mucocutaneous candidiasis (CMC) and hypothyroidism were discovered in 2011. CMC is the recurrent or persistent mucocutaneous infection by Candida fungi, and hypothyroidism results from autoimmune thyroiditis. Patients with these diseases develop other infectious diseases, including viral, bacterial, and fungal diseases, and other autoimmune manifestations, including enterocolitis, immune cytopenia, endocrinopathies, and systemic lupus erythematosus. STAT1-GOF mutations are highly penetrant with a median age at onset of 1 year and often underlie an autosomal dominant trait. As many as 105 mutations at 72 residues, including 65 recurrent mutations, have already been reported in more than 400 patients worldwide. The GOF mechanism involves impaired dephosphorylation of STAT1 in the nucleus. Patient cells show enhanced STAT1-dependent responses to type I and II interferons (IFNs) and IL-27. This impairs Th17 cell development, which accounts for CMC. The pathogenesis of autoimmunity likely involves enhanced type I IFN responses, as in other type I interferonopathies. The pathogenesis of other infections, especially those caused by intramacrophagic bacteria and fungi, which are otherwise seen in patients with diminished type II IFN immunity, has remained mysterious. The cumulative survival rates of patients with and without severe disease (invasive infection, cancer, and/or symptomatic aneurysm) at 60 years of age are 31% and 87%, respectively. Severe autoimmunity also worsens the prognosis. The treatment of patients with STAT1-GOF mutations who suffer from severe infectious and autoimmune manifestations relies on hematopoietic stem cell transplantation and/or oral JAK inhibitors.

Abstract
Autoimmune polyendocrine syndrome type 1 (APS1) is characterized by multiorgan autoimmunity. We aim at characterizing a multi-center Brazilian cohort of APS1 patients by clinical evaluation, searching mutation in the AIRE gene, measuring serum autoantibodies, and investigating correlations between findings. We recruited patients based on the clinical criteria and tested them for AIRE mutations, antibodies against interferon type I and interleukins 17A, 17F and 22. We identified 12 unrelated families (13 patients) with typical signs of APS1 in the proband, and the screening of relatives recognized an asymptomatic child. Candidiasis was present in all cases, and 19 other manifestations were observed. All patients carried one of 10 different mutations in AIRE, being 3 new ones, and were positive for anti-interferon type I serum antibody. Anti-interleukin-17A levels inversely correlated with the number of manifestations in each patient. This negative correlation may suggest a protective effect of anti-interleukin-17A with a potential therapeutic application.

Inherited CARD9 Deficiency: Invasive Disease Caused by Ascomycete Fungi in Previously Healthy Children and Adults. J Clin Immunol 2018; 38:656-693.

Abstract
Autosomal recessive CARD9 deficiency underlies life-threatening, invasive fungal infections in otherwise healthy individuals normally resistant to other infectious agents. In less than 10 years, 58 patients from 39 kindreds have been reported in 14 countries from four continents. The patients are homozygous (n = 49; 31 kindreds) or compound heterozygous (n = 9; 8 kindreds) for 22 different CARD9 mutations. Six mutations are recurrent, probably due to founder effects. Paradoxically, none of the mutant alleles has been experimentally demonstrated to be loss-of-function. CARD9 is expressed principally in myeloid cells, downstream from C-type lectin receptors that can recognize fungal components. Patients with CARD9 deficiency present impaired cytokine and chemokine production by macrophages, dendritic cells, and peripheral blood mononuclear cells and defective killing of some fungi by neutrophils in vitro. Neutrophil recruitment to sites of infection is impaired in vivo. The proportion of Th17 cells is low in most, but not all, patients tested. Up to 52 patients suffering from invasive fungal diseases (IFD) have been reported, with ages at onset of 3.5 to 52 years. Twenty of these patients also displayed superficial fungal infections. Six patients had only mucocutaneous candidiasis or superficial dermatophytosis at their last follow-up visit, at the age of 19 to 50 years. Remarkably, for 50 of the 52 patients with IFD, a single fungus was involved; only two patients had IFDs due to two different fungi. IFD recurred in 44 of 45 patients who responded to treatment, and a different fungal infection occurred in the remaining patient. Ten patients died from IFD, between the ages of 12 and 39 years, whereas another patient died at the age of 91 years, from an unrelated cause. At the most recent scheduled follow-up visit, 81% of the patients were still alive and aged from 6.5 to 75 years. Strikingly, all the causal fungi belonged to the phylum Ascomycota: commensal Candida and saprophytic Trychophyton, Aspergillus, Phialophora, Exophiala, Corynesprora, Aureobasidium, and Ochroconis. Human CARD9 is essential for protective systemic immunity to a subset of fungi from this phylum but seems to be otherwise redundant. Previously healthy patients with unexplained invasive fungal infection, at any age, should be tested for inherited CARD9 deficiency. KEY POINTS • Inherited CARD9 deficiency (OMIM #212050) is an AR PID due to mutations that may be present in a homozygous or compound heterozygous state. • CARD9 is expressed principally in myeloid cells and transduces signals downstream from CLR activation by fungal ligands. • Endogenous mutant CARD9 levels differ between alleles (from full-length normal protein to an absence of normal protein). • The functional impacts of CARD9 mutations involve impaired cytokine production in response to fungal ligands, impaired neutrophil killing and/or recruitment to infection sites, and defects of Th17 immunity. • The key clinical manifestations in patients are fungal infections, including CMC, invasive (in the CNS in particular) Candida infections, extensive/deep dermatophytosis, subcutaneous and invasive phaeohyphomycosis, and extrapulmonary aspergillosis. • The clinical penetrance of CARD9 deficiency is complete, but penetrance is incomplete for each of the fungi concerned. • Age at onset is highly heterogeneous, ranging from childhood to adulthood for the same fungal disease. • All patients with unexplained IFD should be tested for CARD9 mutations. Familial screening and genetic counseling should be proposed. • The treatment of patients with CARD9 mutations is empirical and based on antifungal therapies and the surgical removal of fungal masses. Patients with persistent/relapsing Candida infections of the CNS could be considered for adjuvant GM-CSF/G-CSF therapy. The potential value of HSCT for CARD9-deficient patients remains unclear.

Abstract
Chronic Candida species infection of the skin and mucosal membranes is viewed as a group of disorders all sharing a similar clinical condition, the susceptibility to localized fungal infections, which can be isolated or as a feature associated with various other entities. Although the pathogenesis underlying such a tendency had previously been poorly understood, the last decade has witnessed significant progress in revealing the molecular and immunologic mechanisms involved in antifungal immunity. T(H)17 cells and their specific cytokines (IL-17A and IL-17F cytokines and IL-22) are the main players in conferring antifungal protection. Autoimmune polyendocrinopathy and ectodermal dystrophy and hyper-IgE syndrome are 2 entities caused by different genetic mutations affecting distinct immune pathways but eventually share a similar clinical phenotype of Candida species infection. Impaired T(H)17 responses, although mediated by different mechanisms, seem to underlie this common feature: neutralizing autoantibodies against IL-17A and 1L-22 are involved in patients with autoimmune polyendocrinopathy and ectodermal dystrophy syndrome, whereas abnormal T(H)17 proliferation and IL-17 production are observed in the latter. Although various degrees of T(H)17 dysfunction were also observed in most cases of isolated chronic mucocutaneous candidiasis, only in very few families was a distinct mutation detected (caspase recruitment domain family, member 9 [CARD9]), thus indicating certain forms of chronic mucocutaneous candidiasis as monogenic with a Mendelian pattern of inheritance. Hopefully, these data will open the way for further searches for other genes and for introducing new treatment modalities.

Abstract
Most patients with autoimmune polyendocrine syndrome type I (APS-I) display chronic mucocutaneous candidiasis (CMC). We hypothesized that this CMC might result from autoimmunity to interleukin (IL)-17 cytokines. We found high titers of autoantibodies (auto-Abs) against IL-17A, IL-17F, and/or IL-22 in the sera of all 33 patients tested, as detected by multiplex particle-based flow cytometry. The auto-Abs against IL-17A, IL-17F, and IL-22 were specific in the five patients tested, as shown by Western blotting. The auto-Abs against IL-17A were neutralizing in the only patient tested, as shown by bioassays of IL-17A activity. None of the 37 healthy controls and none of the 103 patients with other autoimmune disorders tested had such auto-Abs. None of the patients with APS-I had auto-Abs against cytokines previously shown to cause other well-defined clinical syndromes in other patients (IL-6, interferon [IFN]-gamma, or granulocyte/macrophage colony-stimulating factor) or against other cytokines (IL-1beta, IL-10, IL-12, IL-18, IL-21, IL-23, IL-26, IFN-beta, tumor necrosis factor [alpha], or transforming growth factor beta). These findings suggest that auto-Abs against IL-17A, IL-17F, and IL-22 may cause CMC in patients with APS-I.

Abstract
Autoimmune polyendocrinopathy - candidosis - ectodermal dystrophy (APECED), also known as autoimmune polyendocrine/polyglandular syndrome type 1 (APS1), is a rare disease caused by mutations in the autoimmune regulator (AIRE) gene pair resulting in absence of active AIRE protein, which is essential for both central and peripheral self-tolerance. The phenotype is widely variable. Apart from the classical triad of mucocutaneous candidosis, hypoparathyroidism and adrenal failure, several other components, some of which are potentially life-threatening, may develop. Due to the unpredictable clinical course, the patients need regular follow-up by a clinician familiar with the disease. Diagnosis is often possible by clinical diagnostic criteria, but in many cases the early clinical picture does not bring it to mind. A novel tool, search for autoantibodies against interferon-omega, enables proof or exclusion of APECED with more certainty than gene analysis. It is highly specific and sensitive for APECED if thymoma and myasthenia gravis are excluded.

Abstract
An 8-year-old boy presented in 1995 with a 2-year history of hypertransaminasemia and hypergammaglobulinemia. Afterwards the patient displayed onychosis with a positive culture test for Candida albicans (CA). Because of the persistence of hypertransaminasemia, a percutaneous liver biopsy was performed showing 'low grade chronic active autoimmune hepatitis' (AIH), positive for liver-kidney microsomal autoantibodies and antibodies to the hepatic autoantigen cytochrome P450-1A2. Immunosuppressive treatment was initiated. In 2003 he developed Addison's disease resulting in the diagnosis of autoimmune polyendocrinopathy candidiasis-ectodermal dysplasia (APECED) syndrome, also known as autoimmune polyendocrine syndrome type 1 (APS1). Anti-17OH hydroxylase antibodies tested negative, anti-21-OH hydroxylase autoantibodies were positive. Among the other relevant organ- and non organ- specific autoantibodies, aromatic L-amino acid decarboxylase (ADDC) autoantibodies and anti-tryptophan hydroxylase autoantibodies were positive. The patient also presented polyuria and polydypsia with diabetes insipidus. Because of the presence of two diagnostic criteria of APS1, mutations in the autoimmune regulator gene (AIRE) were performed, which revealed the presence of a novel mutation (c1314- 1326 del 13/insGT) in exon 11. In conclusion, the diagnosis of APECED should be suspected in any child with minimal hypertransaminasemia, anti-microsomal autoantibodies and Candida albicans onychosis.

Abstract
BACKGROUND The autoimmune regulator (AIRE) gene influences thymic self-tolerance induction. In autoimmune polyendocrinopathy syndrome type 1 (APS1; OMIM 240300), recessive AIRE mutations lead to autoimmunity targetting endocrine and other epithelial tissues, although chronic candidiasis usually appears first. Autoimmunity and chronic candidiasis can associate with thymomas as well. Patients with these tumours frequently also have high titre immunoglobulin G autoantibodies neutralising type I interferon (IFN)-alpha and IFN-omega, which are secreted signalling proteins of the cytokine superfamily involved in both innate and adaptive immunity. METHODS AND FINDINGS We tested for serum autoantibodies to type I IFNs and other immunoregulatory cytokines using specific binding and neutralisation assays. Unexpectedly, in 60/60 Finnish and 16/16 Norwegian APS1 patients with both AIRE alleles mutated, we found high titre neutralising immunoglobulin G autoantibodies to most IFN-alpha subtypes and especially IFN-omega (60% homologous to IFN-alpha)-mostly in the earliest samples. We found lower titres against IFN-beta (30% homologous to IFN-alpha) in 23% of patients; two-thirds of these (from Finland only) also had low titres against the distantly related "type III IFN" (IFN-lambda1; alias interleukin-29). However, autoantibodies to the unrelated type II IFN, IFN-gamma, and other immunoregulatory cytokines, such as interleukin-10 and interleukin-12, were much rarer and did not neutralise. Neutralising titres against type I IFNs averaged even higher in patients with APS1 than in patients with thymomas. Anti-type I IFN autoantibodies preceded overt candidiasis (and several of the autoimmune disorders) in the informative patients, and persisted for decades thereafter. They were undetectable in unaffected heterozygous relatives of APS1 probands (except for low titres against IFN-lambda1), in APS2 patients, and in isolated cases of the endocrine diseases most typical of APS1, so they appear to be APS1-specific. Looking for potentially autoimmunising cell types, we found numerous IFN-alpha(+) antigen-presenting cells-plus strong evidence of local IFN secretion-in the normal thymic medulla (where AIRE expression is strongest), and also in normal germinal centres, where it could perpetuate these autoantibody responses once initiated. IFN-alpha2 and IFN-alpha8 transcripts were also more abundant in antigen-presenting cells cultured from an APS1 patient's blood than from age-matched healthy controls. CONCLUSIONS These apparently spontaneous autoantibody responses to IFNs, particularly IFN-alpha and IFN-omega, segregate like a recessive trait; their high "penetrance" is especially remarkable for such a variable condition. Their apparent restriction to APS1 patients implies practical value in the clinic, e.g., in diagnosing unusual or prodromal AIRE-mutant patients with only single components of APS1, and possibly in prognosis if they prove to predict its onset. These autoantibody responses also raise numerous questions, e.g., about the rarity of other infections in APS1. Moreover, there must also be clues to autoimmunising mechanisms/cell types in the hierarchy of preferences for IFN-omega, IFN-alpha8, IFN-alpha2, and IFN-beta and IFN-lambda1.

Abstract
In two distinct commercial swine herds, poor weight gain and an increased number of animals showing wasting were observed among nursery and growing pigs. Cases of postweaning multisystemic wasting syndrome (PMWS) and infection with Haemophilus parasuis had been previously diagnosed in these herds. One growing wasted pig from each herd was necropsied and showed enlarged lymph nodes. Pseudomembranous material adhered to the dorsum of the tongue, soft and hard palate in case 1, and in case 2, fibrinous material was seen as whitish plaques on the oesophageal surface with hyperkeratosis of the non-glandular stomach. The main histological lesions in both cases were found in lymphoid tissues with a multifocal accentuated lymphohistiocytic infiltrate, areas of lymphoid depletion and intracytoplasmic inclusions in histiocytic cells in lymph nodes and Payer's patches. Focally, extensive ulceration was found in the stratified pavement epithelium of the tongue with necrosis and necrosuppurative infiltrate in case 1; in case 2, there was ulceration in the stomach with lymphohistiocytic infiltrate in the submucosa and ulceration in the mucosa of the oesophagus associated with yeast cells and pseudo-hyphae. Candida albicans was isolated from the oral cavity lesions. Immunohistochemistry of the lymph nodes was positive for porcine circovirus 2 (PCV2). The association between PMWS and mucocutaneous candidiasis reported here supports the potential immunosuppressive state of PMWS infected pigs.

Abstract
Patients with chronic mucocutaneous candidiasis (CMC) are selectively unable to clear the yeast Candida, which results in persistent debilitating infections affecting the skin, nails, and mucous membranes. The underlying defect is unknown. Recent animal studies highlighted the importance of type 1 cytokines in protection against Candida, and previous work suggested that CMC patients may exhibit altered cytokine production in response to Candida. Based on these findings, in this study we investigated cytokine production in CMC patients by assessing a range of inflammatory, anti-inflammatory, type 1, and type 2 cytokines (interleukin-2 [IL-2], IL-4, IL-5, IL-6, IL-10, IL-12, gamma interferon [IFN-gamma], tumor necrosis factor alpha [TNF-alpha]) in whole-blood cultures in response to five different fractions of Candida albicans (carbohydrate, purified mannan, and protein-rich fractions, etc.), as well as non-Candida antigens. Our results demonstrate that cytokine production is deregulated in a Candida-specific way for some cytokines (IL-2, IL-10), is deregulated more generally for other cytokines (IL-12, IL-6, IFN-gamma), and is not markedly altered for still other cytokines (TNF-alpha, IL-4, IL-5). The most notable finding in CMC patients was the markedly impaired production of IL-12 in parallel with dramatically increased levels of IL-6 and IL-10 that occurred selectively in response to Candida. These results suggest that patients with CMC have impaired production of type 1-inducing cytokines (possibly a macrophage or dendritic cell defect?), which could result in an inability to mount protective cell-mediated responses and a failure to clear Candida. Continued tissue damage and inflammation may trigger production of high levels of inhibitory cytokines, such as the IL-10 production seen in our study, which would further reduce production of type 1-inducing cytokines in a positive feedback loop leading to persistent infection.

Abstract
Over the past two decades the genetic bases for virtually all the well-characterized primary immunodeficiency syndromes have been identified. The investigation of rare, poorly differentiated immunodeficiencies is being hampered by a preoccupation of funding agencies with hypothesis-driven proposals that apply poorly in the case of individual patients. Recent studies at our institution in collaboration with groups at NIH have resulted in the identification of two separate kindreds bearing unique mutations in molecules affecting immune function and a chromosomal linkage in a third family. Thus, a potential solution to the funding problem for studies in primary immunodeficiency could lie in the centralization of investigative expertise and support, perhaps within the walls of the National Institutes of Health, as has been done with great success in Europe.

Abstract
This is a case report of 2 patients who were diagnosed to have autoimmune polyglandular disease type 1. Both developed mucocutaneous candidiasis, hypoparathyroidism, vitiligo, and adrenocortical insufficiency. Both were noticed to have subnormal linear growth velocity and delayed bone age. Both showed subnormal stimulated serum growth hormone values indicating growth hormone deficiency. The first case showed favorable response to growth hormone therapy.

Abstract
HISTORY 6 months before admission a 21-year-old woman had developed anogenital condylomata acuminata (CA). Since early childhood she had been treated for primary hypoparathyroidism (PHPT) and recurrent mucocutaneous candidiasis. 5 years before admission corneal clouding had caused visual impairment. Recently, mainly truncal vitiligo with occipital poliosis had developed. INVESTIGATIONS PHPT was confirmed (parathormone level 7.7 mg/l). In addition, liver transaminases were raised (GOT 105.8 U/l, GPT 145.6 U/l, gamma-GT 56.8 U/l), pointing to noninfectious hepatitis. An ACTH stress test could not exclude manifest adrenocortical insufficiency, and thyroid function was also normal. The Merieux Multitest indicated an anergy. DIAGNOSIS, TREATMENT AND COURSE The constellation of test results suggested autoimmune polyglandular syndrome type I. The condylomata were treated by electrocautery and the intestinal candidiasis with amphotericin B suspension. Calcitriol capsules, 0.5 microgram, and calcium gluconate or lactate, 500 and 300 mg respectively, 3 times daily each, were given for the PHPT. CONCLUSION This case demonstrates a complex syndrome which can be recognized early by simple clinical tests. Early diagnosis prevents possible life-threatening complications.

Abstract
Candida albicans, an ubiquity yeast, has several properties which allow it colonize and invade host tissues, often resisting eradication. Acid proteinase is the virulence factor. Bacterial proteinases are widely used in the detergent industry and the role of occupational exposure to enzymes in the development of mucocutaneous candidosis warrants investigation. A case of candidosis is reported in a worker employed in a detergent factory in whom there was no evidence of any kind of immunosuppression. The relationship between occupational exposure and illness is analyzed.

Abstract
Forty-one patients routinely attending the Oxford Haemophilia Centre entered a controlled, blind investigation in order to determine whether HIV antibody status was related to the presence of skin disease. Twenty-four of the 41 patients (58.5%) were HIV antibody positive and none had any general symptoms. Comparison of the HIV antibody positive group with the HIV antibody negative group and with non-haemophiliac controls showed an increased prevalence of four HIV-associated dermatoses: 11 patients had seborrhoeic dermatitis (10 HIV antibody positive and one HIV antibody negative (P less than 0.05 chi 2 test], eight patients had folliculitis (six HIV antibody positive), four patients had mucocutaneous candidiasis, all were HIV antibody positive, and three patients had onychomycosis, all were HIV antibody positive. None of these conditions was seen in a group of 16 non-haemophiliac controls. These findings are different from those reported from a similar study of comparable groups of homosexual men and these results may be further evidence to support the belief that the behaviour of HIV infection differs between haemophiliacs and other risk groups.

Abstract
Idiopathic hypoparathyroidism is a rare disorder produced by parathyroid hormone deficiency of unknown cause. It is often associated with other endocrine abnormalities. Patients with idiopathic hypoparathyroidism frequently develop ectodermal disease, including dry, rough skin: coarse, brittle hair; and lusterless, distally split nails. All of these complaints are relatively common in a dermatologic practice. Chronic mucocutaneous candidiasis is also a manifestation of idiopathic hypoparathyroidism. A patient is presented with a prominent ectodermal dysplasia and a chronic mucocutaneous candidiasis that were due to the underlying idiopathic hypoparathyroidism. A brief review of idiopathic hypoparathyroidism is included, as well as the implications of this diagnosis in terms of differential diagnosis, associated endocrine disorders, and therapy.

Abstract
The two most important pathologic conditions leading to mycotic opportunistic infections in children are impairment of mechanisms of defense due to immunosuppressive drugs and congenital defects of immunity. Other circumstances belong to pediatrics such as prematurity or cystic fibrosis. A few examples are chosen to illustrate these situations: congenital candidiasis, chronic mucocutaneous candidiasis, chronic dermatophytic disease, neonatal candidemia, mycotic infections in chronic granulomatous disease and aspergillosis in cystic fibrosis.

Abstract
Due to the high frequency and variety of the mucous cutaneous signs, the dermatologists are facing many cases of AIDS. These signs are no specific but only the consequence of a cellular immunodeficiency; they can be encountered in other situations, more specifically after an immunosuppressive treatment. Therefore, the diagnosis can be evocated only from AIDS association of the mucous cutaneous manifestations with other clinical, epidemiological and biological signs. The Kaposi's sarcoma which is present in 35 of the observed AIDS is in fact the cutaneous aspect of a cellular immunodeficiency. In one hand, the clinical lesions have a quiet involvement without any associated disorder. At the opposite, cutaneous lesions have a fulminant dissemination associated to lymph nodes and/or visceral involvement and opportunistic infections: these cases have a very severe prognosis. Kaposi's sarcoma is not observed in the cases of post-transfusional AIDS. Chronical herpes occurs frequently during this syndrome, the lesions lasting above six weeks associated to anal or genital localizations. Chronical candidosis, clinically associated, has a mucous cutaneous localization with involvement of the oral cavity, progressively extending digestive system and respiratory tracts.
