Paracoccidioidomycosis with sarcoid-like lesions:a diagnostic challenge

We report herein a clinical presentation of sarcoid-like PCM, initially diagnosed as tuberculoid leprosy. This rare type of PCM is often mistaken for other types of chronic granulomatous diseases. Diagnosis was confirmed after 4 years when a special stain analysis helped in the identification of the specific etiologic agent.

By SAURABH JHA, MD Slumdog TB No one knows who gave Rahul Roy tuberculosis. Roy’s charmed life as a successful trader involved traveling in his Mercedes C class between his apartment on the plush Nepean Sea Road in South Mumbai and offices in Bombay Stock Exchange. He cared little for Mumbai’s weather. He seldom rolled down his car windows – his ambient atmosphere, optimized for his comfort, rarely changed. Historically TB, or “consumption” as it was known, was a Bohemian malady; the chronic suffering produced a rhapsody which produced fine art. TB was fashionable in Victorian Britain...

Discussion Facial nerve palsy has been known for centuries, but in 1821 unilateral facial nerve paralysis was described by Sir Charles Bell. Bell’s palsy (BP) is a unilateral, acute facial paralysis that is clinically diagnosed after other etiologies have been excluded by appropriate history, physical examination and/or laboratory testing or imaging. Symptoms include abnormal movement of facial nerve. It can be associated with changes in facial sensation, hearing, taste or excessive tearing. The right and left sides are equally affected but bilateral BP is rare (0.3%). Paralysis can be complete or incomplete at prese...

Discussion Hypopigmentation can be worrisome for many families because of cosmesis and the worry that “something is wrong.” The normal natural changes in skin-tone over the year due to different light exposure and wide variations within individuals is not something that many people are aware of. Post-inflammatory hypopigmentation is a common cause of hypopigmentation. Vitiligo is the most common cause of depigmentation. Vitiligo is an acquired, depigmenting disorder with typical lesions appearing as milky white macules with distinct margins that are not scaly. Hair (including eyebrows and eyelashes) can be dep...

Abstract Granuloma multiforme (GM) is a chronic granulomatous skin condition which is clinically characterised by annular lesions mainly over sun-exposed areas and histologically by focal necrobiosis and histiocytic granulomas. Its significance lies in the fact that it can clinically resemble tuberculoid leprosy and hence it can be missed. Here, we report a case of GM from India in a 55-year-old female agriculturist, with multiple asymptomatic large annular rings of papules over the photo-distributed areas. Histopathology helps in confirming the diagnosis and in differentiating it from similar clinical and histolo...

Background: More than 200,000 new cases of leprosy are detected worldwide annually. Owing to the increment of the immigration flows from endemic areas, leprosy cases might be more frequently observed in nonendemic areas as well. Physicians commonly have difficulty in differentiating tuberculoid form of leprosy (TL) from sarcoidosis ’ cutaneous manifestation. Histologically in TL, epithelioid granulomas are well defined with evident lymphocyte rim distributed around the appendages and nerves, whereas in sarcoidosis, granulomas are classically naked.

This article provides a current overview of the dermatoscopic features of the main noninfectious and infectious CGDs, including sarcoidosis, necrobiosis lipoidica, granuloma annulare, rheumatoid nodules, and leishmaniasis. Other, less common, CGDs are briefly addressed, including granulomatous rosacea, acne agminata, and leprosy.

Conclusion: The use of auxiliary tests including real-time PCR to amplify an M leprae-specific DNA sequence, enzyme-linked immunosorbent assay, and dipstick detection of serum antibodies specific to M leprae antigens are good methods to obtain a correct diagnosis of BT leprosy.

We describe a patient presenting with neurologic symptoms referable to a persistent unilateral cavernous sinus MRI abnormality, initially thought to be consistent with Tolosa-Hunt syndrome, that was clinically but not radiographically responsive to steroids. Following reevaluation due to the presence of new symptoms, pathology revealed that the abnormality was most consistent with chordoma, a rare skull based tumor. In patients with a presumed diagnosis of Tolosa-Hunt syndrome, close clinical and radiographic follow-up is imperative, with early consideration for biopsy in patients that fail to respond to treatment both cli...

ABSTRACT BackgroundMore than 200,000 new cases of leprosy are detected worldwide annually. Physicians commonly have difficulty in differentiating tuberculoid form of leprosy (TL) from sarcoidosis’ cutaneous manifestation. MethodsSkin biopsies of 33 patients with TL and 24 with sarcoidosis were reviewed on hematoxylin and eosin and Gomori stained sections, in order to find reliable criteria for distinguishing one disease from another. ResultsNine of the 24 features analyzed presented significant predictive value for diagnosis (p

As the rate of obesity and the prevalence of type 2 diabetes increase, diabetic neuropathy is the most common cause of peripheral neuropathy. Many systemic disorders with metabolic origin, like amyloidosis, hepatic failure, vitamin deficiencies, uremia, lipid metabolism disorders,...
