Receive Second Opinions from Our Lab

Obtaining a second opinion is not an uncommon decision. In fact, second opinions can be very helpful to your physician in the development of a treatment plan specifically for you.

A pathology second opinion can help you be sure that your diagnosis and disease characteristics are correct. This is very important because doctors base their treatment advice on your pathology report. If your pathology report is wrong, you might get the wrong care. Every so often it can become difficult for pathologists to give a clear-cut diagnosis. So you may get conflicting pathology reports. In this case, it is especially important to learn as much as you can about your specific diagnosis.

How It Works

To get a pathology second opinion you must have your tissue slides sent to our pathologists specializing in your specific condition. You can arrange to have this done on your own, which does not require your doctor’s permission/referral to have a pathology second opinion, however you may need to work with your insurance company to determine the financial responsibility. You can also ask your physician to request one from us. All you need to do is contact our office at (813) 870-4206. We will have our expert staff instruct you or your physician on how to handle the referral.

Your doctor will receive the second opinion test results as they become available. It may take a few days to a few weeks to receive the full report and the timing will depend on the type of testing needed. You are entitled by law to receive a copy of your pathology report. However, you should expect the report to contain highly technical medical terms. It is important for you to ask your doctor to explain the pathology report results and what they mean.

BayCare Esoteric Laboratory

The Department of Pathology within the BayCare health system has a single, core laboratory for specialized testing that includes cytogenetics, molecular diagnostics, flow cytometry, and special chemistry as well as containing the consolidated microbiology laboratory for the system. Dr. Bischof of Associated Pathologists has served as the medical director for this facility since its opening in 2012. Dr. Erdman functions as the assistant medical director, and Dr. Carlos Dalence is a consulting pathologist for the flow cytometry laboratory.

The cytogenetics laboratory performs chromosome analysis of bone marrow specimens for both oncology and constitutional evaluation. Microarray analysis is also performed for constitutional genetic analysis. This laboratory performs a wide range of FISH (fluorescent in-situ hybridization) assays, including some assays targeted for constitutional disorders. The majority of the FISH assays however are used for analysis of hematological neoplasms, including acute leukemias as well as aggressive B-cell lymphomas. HER2 (ERBB2) amplification is performed by FISH for solid tumor analysis to aid in the evaluation for targeted therapy.

The molecular diagnostics laboratory performs multiple assays for infectious disease, germline testing, and cancer diagnosis and prognosis. There is a broad range of assays ranging from high-throughput viral load instruments to specialized cancer testing where solid tumor specimens may be macro-dissected prior to molecular analysis to ensure appropriate tumor is analyzed. Much of the initial COVID testing for the Tampa Bay area was performed in this laboratory, which eventually grew to provide high volume testing for the entire community. The laboratory is currently expanding next generation sequencing (NGS) capability for solid tumors and myeloid neoplasms.

The flow cytometry laboratory’s test menu includes both pediatric and adult leukemia and lymphoma analysis, B-cell and T-cell subset analysis, and paroxysmal nocturnal hemoglobinuria (PNH) testing. This laboratory performs both routine flow cytometry analysis as well as STAT testing for urgent cases to expedite patient care. The special chemistry laboratory includes protein and hemoglobin electrophoresis, high-volume allergen testing, autoimmune testing as well as the Quantiferon (Tuberculosis) assay.

Finally, the core microbiology laboratory performs all aspects of infectious disease testing ranging from high volume urine and blood culture assays to specialized testing for fungi and acid-fast bacilli. This laboratory includes state of the art mass spectrometry identification of microorganisms. The core laboratory also oversees rapid, molecular infectious disease testing performed within the BayCare hospitals. 

As all of this specialized testing is in one facility, the BayCare esoteric laboratory is fully integrated allowing for communication, coordination and rapid analysis of specimens, particularly for hematological neoplasms. This laboratory also works closely with pathologists and clinicians in BayCare for appropriate and timely analysis of all specimen types that are received, and it works to update the test menu for appropriate clinical need. The laboratory is customer focused, both for physicians within BayCare as well as for the patients that are served through this facility. 

BayCare’s test compendium can be viewed to review all the testing performed within this healthcare system, including assays performed at the Esoteric laboratory here

Children’s Oncology Group Treatment Centers

The origins of Associated Pathologists and the St. Joseph’s Hospital Pathology Department arise from the mists of the early 1950’s and decisions made by the Sisters of St. Francis of Olean, New York. At that time the Sisters, who both owned and operated St. Joseph’s Hospital at its original downtown Tampa location, determined that laboratory and pathology workload considerations mandated a full-time pathologist. Their search yielded Dr. Robert J. Davis, a graduate of the Yale University Pathology Residency program. Dr. Davis accepted the position, becoming the first and only pathologist at St. Joseph’s Hospital for the next 15 years, his entire term of service extending to 1979.

Across the United States, more than 200 children’s cancer centers that have met the quality assurance standards established by the National Cancer Institute (NCI) comprise a network of hospitals known as the Children’s Oncology Group (COG).  This group of institutions work together to implement improved therapies developed through collaborative clinical-translational research, including large-scale clinical trials, that are funded by the NCI.  Treatment protocols that are developed through the COG’s clinical trial research network ensure that children with similar diagnoses treated at COG institutions will receive the same treatment, regardless of where they live in the United States.

COG’s research studies encompass hematologic malignancies, solid tumors, central nervous system tumors, and rare cancers.  Hematologic malignancies include the most common childhood cancer, acute lymphoblastic leukemia, as well as acute myeloid leukemia, non-Hodgkins lymphomas, and Hodgkins lymphoma.  Pediatric solid tumors studied include neuroblastoma, tumors of bone (Ewings sarcoma, osteosarcoma), tumors of the kidney (Wilms tumor), rhabdomyosarcoma, and other soft tissue sarcomas.

Central nervous system (brain) tumors are the second most common form of childhood cancer.  COG conducts research in children with medulloblastoma, ependymoma, brainstem gliomas, low and high-grade gliomas, and germ cell tumors.  The large multi-site structure of COG also allows it to conduct research into very rare childhood cancer, including retinoblastoma, hepatoblastoma, and other tumors.  In addition to disease specific research, COG conducts studies in developmental therapeutics (new cancer drug development), supportive care, epidemiology, stem cell transplantation, behavioral sciences, and survivorship.
