PathologyWatch Selected to Participate in AWS Healthcare Accelerator: Global Cohort for Workforce

PathologyWatch, the groundbreaking leader of digital dermatopathology services, has been chosen as one of a select group of 23 startups to participate in the global AWS Healthcare Accelerator: Global Cohort for Workforce.

This AWS Healthcare Accelerator is a four-week technical, business, and mentorship program for startups seeking to use AWS to improve healthcare workforce training, retention, and deployment. This opportunity, which begins in April and runs through the summer, will support PathologyWatch’s efforts to digitally optimize pathology workflows, providing tools that augment dermatopathology resources and interface directly with EHRs. PathologyWatch’s academic-level dermatopathologists can review and provide interpretations for digital slides remotely, supporting clinical decision-making while reducing costs and allowing workplace flexibility.

“We are honored to be one of a few companies chosen for the AWS Healthcare Accelerator program,” says Dan Lambert, CEO and cofounder of PathologyWatch. “Digital pathology is the key to providing quality healthcare solutions to so many underserved areas of the world, including the rural United States. Our mission at PathologyWatch is to leapfrog technology forward in the digital pathology space by connecting individual offices with dermpath experts throughout the world. We believe the AWS Accelerator program can help us in that journey.” 

Curriculum of the AWS Healthcare Accelerator will offer opportunities such as hands-on AWS Cloud and technical training, mentorship from healthcare leaders, and exposure to AWS customers and members of the AWS Partner Network. PathologyWatch, which is seeking to advance solutions for addressing urgent challenges facing the healthcare workforce, will also receive AWS computing credits and opportunities to speak with investors and industry experts, including at a Demo Day, where PathologyWatch’s solutions will be showcased.

“Solutions to help clinicians as well as other office and technical staff in healthcare are needed urgently and globally,” says Dr. Rowland Illing, chief medical officer and director of International Public Sector Health at AWS. “We know that advancing cloud- and technology-enabled approaches can alleviate some of the burden, and we’re proud to be convening standout startups and healthcare leaders in this first-ever global Accelerator to do that.”

“We do a significant amount of AI and deep learning research on AWS. They’ve been a great partner,” says Lambert. “The sample volume that we process daily has gone up almost 200% over the past couple of years, and AWS has been able to scale with us. It’s nice having a flexible on-demand hosting solution available immediately.”

Healthcare workforce shortages are at crisis levels, driven by burnout, shrinking budgets, and the aftermath of a worldwide pandemic. A shortfall of 10 million healthcare workers is forecast by 2030. As a result, patients may go untreated or experience delays in care, and healthcare workers need support now more than ever. 

In the field of pathology, there is a significant shortage of qualified pathologists, both in the US and worldwide. PathologyWatch is using digital tools to help cover this physician gap, allow pathologists to work remotely, and reduce burnout.

2023 Annual American Academy of Dermatology (AAD) Weekend Recap

We had a wonderful time at AAD’s annual conference held last weekend in New Orleans. With 8,500 health care professionals and over 16,000 total registrants, The Big Easy was bustling with the latest in pathology resources and expertise.

Here are a few of the highlights from the PathologyWatch team:

This year’s booth enjoyed a vibrant stream of dermatologists who were interested in learning about dot., the dermpath virtual assistant that helps derms to manage case workloads, view digital images and case files, create detailed pathology reports, and collaborate with colleagues.

Dr. Cacey Peters was on hand to demonstrate how dot. makes reviewing and annotating digital slides a snap for Derms and DermPaths. He also met with more than a few starstruck fans of his popular #GettingUnderYourSkin social media videos.

Though it isn’t polite to brag, we put our best foot forward by producing the show’s most memorable swag: custom socks featuring verruca vulgaris histology. That’s right, we gave warts to hundreds of happy derms.

In addition, a hot pot of Starbucks coffee is just what the doctors ordered to stay alert and keep their eyes on the prize. 

Friday evening we hosted our infamous annual AAD happy hour at Rosie’s On The Roof, which is located on top of the historic Higgins Hotel. Hundreds of Derms braved stormy conditions to join us for a classic fais do-do with bottomless hors d’oeuvres and drinks. 

Falling on St. Patrick’s Day, the place was packed with festive pathologists looking to let off a little steam and socialize between conference sessions. 

The patio’s city views offered the perfect location to reunite with familiar faces and make new friends.

At the end of the night, we gave away special edition “Show Me Some Skin” T-shirts, with the words “Don’t Worry, I’m a Dermatologist” emblazoned on the back. Based on the frenzy they created, the shirts will definitely be returning for AAD in San Diego 2024.

We also handed out custom Mardi Gras beads to get everyone in the spirit of the city’s rich traditions.

Looking back at our experience in New Orleans, we couldn’t be happier to be a part of this inspiring community. It was a joy to meet, answer questions, and share our vision with so many talented Derms. 

2023 promises to be a herald year for PathologyWatch, our customers and partners as we continue making great strides in the development of technology and workflows that enhance patient outcomes.

Journal of Pathology Informatics: High-Fidelity Detection, Subtyping, and Localization of Five Skin Neoplasms Using Supervised and Semisupervised Learning

Pathologywatch Implements AI Technology That Detects 5 Skin Lesion Types with Higher Sensitivity than Previously Published AI Model

Authors: James Requa, Tuatini Godard, Rajni Mandal, Bonnie Balzer, Darren Whittemore, Eva George, Frenalyn Barcelona, Chalette Lambert, Jonathan Lee, Allison Lambert, April Larson, Gregory Osmond


  • Including a large dataset of hand-drawn annotations increases the sensitivity of AI.
  • Integrated supervised and semisupervised learning is superior to other AI models. 
  • Multilevel training permits subtyping, localization, and margin detection.
  • Dermpath involvement in model development can ultimately improve model performance.
  • Increased confidence in AI-assisted diagnoses can lead to improved patient care.



Skin cancer is the most common malignancy diagnosed worldwide, accounting for over 30% of all cancer diagnoses. Equally troublesome is the 77% increase in nonmelanoma skin cancers over the last several decades and a 250% increase in melanoma cases in children, adolescents, and young adults since 1973. 


The goal of this study was to create an AI model that detects and classifies skin lesions with a higher degree of sensitivity than previously demonstrated. This AI model (i.e., Mihm) has the potential to match and eventually surpass expert pathologists and improve clinical workflows.


We produced an end-to-end multilevel skin detection system by combining supervised learning (SL) with semisupervised learning (SSL). This system detects five main types of skin lesions with high sensitivity and specificity. In addition, it detects subtypes while also localizing and providing margin status to evaluate the proximity of the lesion to nonepidermal margins. 

Supervised Training Subset

  • 2,188 random WSIs collected by PathologyWatch laboratory between 2013 and 2018
  • Weekly supervised subset consisting of 5,161 WSIs from daily case specimens

Validation Set

  • 250 curated daily case WSIs from PathologyWatch’s tissue archives
  • Included 50 “mimickers”

Testing Set

  • Composed of noncurated daily case specimens collected from PathologyWatch labs between July 20, 2021, and August 20, 2021


By running the testing set through the Mihm Evaluation Pipeline, we could assess the performance characteristics of our AI model. 

PathologyWatch AI

Our multilevel detection algorithm (patch-level, ROI-level, WSI-level) can subtype lesions with an AI overlay in the front-end digital display that localizes diagnostic ROIs and reports on margin status by detecting overlap between lesions and nonepidermal tissue margins.


This AI model, which is the result of collaboration among a team of dermatopathologists, detects five skin lesion types with higher sensitivity than previous AI models. It also provides end users with valuable insights in subtyping, localization, and margin status in a front-end digital display.

This end-to-end system can improve pathology workflows by doing the following:

  • Increasing diagnostic accuracy
  • Expediting the course of patient care
  • Improving patient outcomes
