Presentation
Comment Here Reference: Cryptococcus neoformans and gattii Board review style question #2 A 67 year old woman presented with a solitary lung nodule. Biopsy showed variably sized yeast with no discernible capsule. [pathologyoutlines.com]
Sign In A 36-year-old man presented to the emergency department with a 2 week-history of headache, photophobia, and fever. [nejm.org]
(A,B) Yeast in the beginning of the budding process presents a modest cell wall delamination in the specialized region (SR). [frontiersin.org]
He presented a history of chronic smoking, grade III obesity, hypertension, chronic atrial fibrillation, dyslipidemia, peripheral obstructive arterial disease and lipodystrophy. [bjid.org.br]
Meningeal cryptococcosis is the most frequent clinical presentation of this disseminated mycosis. The oral mucosa involvement is extremely unusual. Case report We present a case of cryptococcosis with an unusual clinical form. [elsevier.es]

Administration of intravenous administration of amphotericin B and oral fluconazole for two weeks. This is then followed with oral fluconazole for 10 weeks and a lower dose a year to improve the patients’ CD4 count. [microbenotes.com]

It is a compound similar to the one that makes moles and freckles dark brown. For Cryptococcus, melanin offers protection from a process called oxidative killing. [scq.ubc.ca]

Treatment
Individuals with compromised immune systems, or under immune suppressive therapy, should be given prolonged drug treatment to prevent relapses. [rarediseases.org]
Nevertheless, after 15 days of treatment, the patient presented acute renal injury and anemia. Thus, his antifungal treatment was changed to amphotericin lipid complex and fluconazole 800mg/day. [bjid.org.br]

Mycological failure after 2 weeks of induction is recognized as a factor of bad prognosis, which requires continuation of the induction therapy (79). [jci.org]
High antigen securities generally correlate with disease severity and likewise a decrease corresponds to a good prognosis. [mycology.imedpub.com]
Etiology

The results of the biopsy were unspecific and no etiological diagnosis was identified. After this procedure, the post-surgical wound never completely healed. [bjid.org.br]
Some years ago, it was considered that the etiologic agent of this disease was a single species, Cryptococcus neoformans, which had two varieties: C. neoformans var. neoformans, and C. neoformans var. gattii. [elsevier.es]
