We reviewed biopsy records for 37 cases of oral histoplasmosis for patient characteristics, clinical features, and histopathologic findings. These represented cases diagnosed in the Division of Stomatology, Institute for Medical Research, Kuala Lumpur between July 1967 and October 1994. All were male patients who ranged in age from 11 to 79 years (mean age, 56.7 years). There were 40.6% Malays, 37.8% Chinese, 18.9% Indians, and 2.7% other races. Five patients with mouth lesions as the initial presenting lesions were proven to be cases of disseminated histoplasmosis. In the remaining cases apart from the biopsy-proven oral histoplasmosis lesions, the extent of the disease elsewhere was unknown. The majority of these lesions involved the gingiva, tongue, and palate in decreasing order of frequency. The most frequent presenting symptom was oral mucosal ulceration. Squamous cell carcinoma and tuberculosis were the two most common clinical differential diagnoses. Our present findings compare favorably with published reports from other regions.

Oral histoplasmosis presenting as oral ulcer in a non-HIV patient

Rahman MT, Bakar NH, Philip R, Shamsudin AR

Southeast Asian J. Trop. Med. Public Health, 2004 Jun;35(2):388-90.

PMID: 15691142

A 40-year-old man presented with chronic mouth ulcer for the last six months. Histopathological examination of the biopsy from the lesion confirmed a diagnosis of histoplasmosis. Although histoplasmosis commonly manifests in immunocompromized patients, like HIV, the present case was negative for HIV. Histoplasmosis is endemic in certain parts of the world and it is comparatively rare in the South Asian region, particularly Malaysia. Thirty-seven cases of histoplasmosis were reported from Malaysia (Ng and Siar, 1996), between July 1967 and October 1997. Despite the apparent rarity of the disease, clinicians and pathologists should be aware of the possibility of histoplasmosis when cases of oral ulcer are encountered.

Histoplasmosis is a systemic fungal infection caused by inhalation of Histoplasma capsulatum, which is mainly found in bird and bat droppings. Oral manifestation of histoplasmosis may be the only initial manifestation of the disease or associated with chronic disseminated histoplasmosis. The first review of oral histoplasmosis among Malaysian population from 1967 to 1994 (27 years) revealed the occurrence of 37 cases, reported by Ng and Siar in 1996. This current study is the updated overview of oral histoplasmosis cases in Malaysia. The objective of the study was to review and describe clinical and demographic profile of oral histoplasmosis in Malaysia and to correlate histopathological features of oral histoplasmosis with patient's immunity status. We reviewed oral histoplasmosis cases diagnosed in Stomatology Unit, Institute for Medical Research (IMR), Kuala Lumpur from 1995 until 2016. The data was retrieved from the Oral Pathology Information system (OPIS) Stomatology Unit, IMR, which is the largest oral pathology database in Malaysia. Information regarding patients' sociodemographic data, medical illness, clinical presentation, histopathological features, and referring healthcare institutions was extracted from the clinical information which accompanied the biopsy request form. A total of 39 cases of oral histoplasmosis were identified from 1995-2016. Majority of them were male (89.7%). The age ranges from 29 to 85 years with mean age of 57.8 years. Almost half of them were Malays (51.3%), followed by Chinese (33.3%), Indians (7.7%), and other races (7.7%). The most common sites of oral histoplasmosis were tongue, gingiva, palate, and alveolar ridge. The main clinical presentation was ulcer (61.5%) whereas 38.5% presented clinically as swelling. 17.9% of patients were seropositive for human immunodeficiency virus (HIV), 12.8% had tuberculosis, 10.3% had diabetes mellitus, and 2.6% with hepatitis C. The incidence of oral histoplasmosis should raise suspicion of hidden immunodepression and may be the first manifestation of acquired immunodeficiency syndrome (AIDS). Early recognition and diagnosis is crucial to reduce risk of morbidity and mortality.

Histoplasmosis caused by the fungus Histoplasma capsulatum is often lethal in patients with AIDS. Urine antigen testing is highly sensitive and much quicker for diagnosis than culture. Histoplasmosis has a patchy and incompletely appreciated distribution around the world especially in South East Asia. We conducted a systematic literature review of cases of all disease forms of histoplasmosis in SE Asia, not including the Indian sub-continent. We also reviewed all histoplasmin skin test mapping studies to determine localities of exposure. We found a total of 407 cases contracted or likely to have been contracted in SE Asia. Numbers of cases by country varied: Thailand (233), Malaysia (76), Indonesia (48) and Singapore (21), with few or no cases reported in other countries. Most cases (255 (63%)) were disseminated histoplasmosis and 177 (43%) cases were HIV associated. Areas of high histoplasmin skin test sensitivity prevalence were found in Myanmar, the Philippines, Indonesia, Thailand and Vietnam - 86.4%, 26.0%, 63.6%, 36.0% and 33.7%, respectively. We have drawn maps of these data. Further study is required to ascertain the extent of histoplasmosis within SE Asia. Diagnostic capability for patients with HIV infection is urgently required in SE Asia, to reduce mortality and mis-diagnosis as tuberculosis.

Fulltext Laryngeal histoplasmosis: an occupational hazard

Teoh JW, Hassan F, Mohamad Yunus MR

Singapore Med J, 2013 Oct;54(10):e208-10.

PMID: 24154590

Isolated laryngeal histoplasmosis is a very rare entity. It has variable clinical presentations that might mimic both benign and malignant lesions, and is usually associated with pulmonary and other disseminated forms of histoplasmosis. Herein, we report a case of primary laryngeal histoplasmosis without the involvement of other systems in a 70-year-old Chinese man, who previously worked as a miner. He presented with a history of hoarseness for two months, with no other associated symptoms. Direct laryngoscopy revealed irregularity of the posterior one-third of both vocal folds. Histopathological examination revealed the presence of Histoplasma capsulatumon periodic acidSchiff and Grocott's methenamine silver staining. The lesion resolved after one month of oral itraconazole treatment. However, the patient had to complete six months of antifungal treatment to prevent recurrence.

We report a case of disseminated histoplasmosis, initially diagnosed from gut nodule colonoscopically, along with evidence of lung disease. Subsequently he developed Addisonian crisis due to adrenal involvement. Lessons were learnt from the importance of detailed history-personal and social/family, as well as psychosocial aspects of illness. Public health measures to reduce bird dropping (and thus possibility of histoplasmosis) are discussed.

Histoplasmosis presenting with progressively worsening backache--a case report

Lachmanan SR, Haniza O, Hisham AN, Subramaniam J, Merican I

Ann Acad Med Singap, 2001 Nov;30(6):656-8.

PMID: 11817299

INTRODUCTION: Bilateral adrenal enlargement is often the result of disseminated malignant disease, and this diagnosis is particularly likely in a patient with severe weight loss. We describe a case with bilateral adrenal enlargement presenting with progressively worsening backache as a prominent symptom.

CLINICAL PICTURE: A 55-year-old man presented with intermittent low back pain which was progressively worsening, fever, anorexia, low back pain and a 10-kg weight loss. He had underlying diabetes mellitus and ischaemic heart disease. He gave a history of travel to caves for worship. Clinically, the most significant findings included nodular lesions in the anterior fauces and left palatoglossal region. Computed tomographic scan revealed bilateral adrenal masses. Biopsies were taken from the palatal nodules, which revealed histiocytes with numerous histoplasma organisms.

TREATMENT: He was commenced on itraconazole 200 mg daily for a period of 9 months. There was a dramatic initial response with settling of his fever and this was followed by subjective improvement in his well-being.

OUTCOME: He is presently on follow-up and has completed 9 months of itraconazole therapy with resolution of all his symptoms and has gained about 10 kg of weight.

Med J Malaysia, 2005 Aug;60(3):386-8.

PMID: 16379201

Primary histoplasmosis of the larynx is not a common disease. Most cases of laryngeal histoplasmosis results from hematogenous spread of disseminated histoplasmosis usually originating from pulmonary infection by Histoplasma capsulatum. We report a 52-year-old male chronic smoker who had prolonged hoarseness and was initially diagnosed with laryngeal carcinoma. However, biopsy of the laryngeal mucosa confirmed the diagnosis of histoplasmosis. There were no signs of pulmonary or systemic involvement. Treatment with intravenous amphotericin B was given for a week and oral ketaconazole was given for a month with complete resolution of symptoms.

Histoplasmosis in Malaya

Ponnampalam JT

Br J Dis Chest, 1964 Apr;58:49-55.

PMID: 14152216

A survey of 227 patients from 5-60 years of age revealed the presence of positive histoplasmin skin tests in 10.5 per cent. and positive complement-fixation tests in 19-8 per cent. Sputum from 13 of the 37 patients who had a positive complement-fixation test were cultured for H. capsulatum but with negative results. Exposure to infection by the fungus is equally distributed among the different race and age groups. A careful and constant watch should be kept for histoplasmosis in all chest hospitals as a certain number of cases may be present. It tends to elude diagnosis unless specially sought as it resembles the clinical picture of tuberculosis or other granulomatous disease. It presents a field for further investigation and research in Malaya.

PMID: 2344324

A 59-year-old Chinese man presented with a three month history of penile ulcers and abdominal pain. Syphilis and a gastric malignancy were diagnosed clinically. Biopsy of the genital and stomach ulcers revealed histiocytic granulomata containing numerous intracellular fungal bodies. Histoplasma capsulatum was subsequently cultured from the penile ulcer. Antifungal therapy was instituted. However the patient's general condition deteriorated rapidly and he died within two weeks of admission. A post-mortem liver biopsy showed numerous intracellular fungi.

PMID: 2392708

A 51-year old man presented with a persistent tongue ulcer, fever, cervical lymphadenopathy and hepatomegaly. The diagnosis was initially thought to be tuberculosis. This led to the initiation of antituberculous chemotherapy to which the patient failed to respond. The correct diagnosis of histoplasmosis was made after the detection of Histoplasma capsulatum on further review of the tongue ulcer biopsy specimen. He responded to treatment with amphotericin B.
